Satellite P305-S8820 doesn't boot - POST "BLACK SCREEN" will not boot CD's

Question: Satellite P305-S8820 doesn't boot - POST "BLACK SCREEN" will not boot CD's

When the HDD is connected Vista will not boot, no matter the boot order. Instead it just shows a black screen with no cursor. The provided recovery discs will not boot. I removed the HDD and ran a disc scan to see if the disc was going bad, no dice, the HDD is good and works fine via usb-sata on another computer.

I inserted just the toshiba recovery disc, No HDD, and it booted. I connected the now external HDD and vista attempts to boot BSOD, Tried safe mode, last known, everything, nothing works, all get an BSOD which dissapears too fast for me to read.

I searched for a dump file on my other computer and was unsuccessful. When the HDD is connected via usb vista attempts to boot and the toshiba cd now works, however, it will not perform a full toshiba factory install it cannot find the HDD??? I am a windows power user and have years of experience with x86 programming and windows 32-bit operating systems but I am stumped. Bad Ram? Bad Sata? Bad HDD? Bad CD/DVD? this is vista home premium.

I do not want to reformat and lose all of my data "I AM A REAL "IT" not some idiot computer user" no offense to all others out there but I refuse to just "format and forget it" The tools provided used command prompt to rebuild the BCD and this doesn't work either, and the automatic repair does nothing, recovery doesn't work as it says there are no recovery points, I am frustrated beyond words.

Lastly, this operating system is just horrible, I was once the "proud" owner of a copy of Windows ME and it didn't give me half of the problems that this operating system does.

I am fed up with this, and am half tempted to demand my money back for my computer, It sould not be the responsibility of the user to trouble shoot/ fix these problems, they should have been addressed before the product was released.

I am at a loss. Please help.



Thanks,



Kevin

Preferred Solution: Satellite P305-S8820 doesn't boot - POST "BLACK SCREEN" will not boot CD's

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Satellite P305-S8820 doesn't boot - POST "BLACK SCREEN" will not boot CD's

I'm a bit confused with the info given, but if you cant restore/repair Windows, then what you should do is backup your data to another PC using a USB Adapter, then run Recovery on the internal HDD in the P305.

You should also update the BIOS.

Hi All,

If I purchase Microsoft Windows 7 Home Premium Upgrade Family Pack (3-User) (DVD-ROM), for my toshiba P305-S8820.

1. Will I be able to perform a clean install by reformatting the disk?
2. Is there a utility from Toshiba, that will go find all the drivers for Windows 7?
3. Which drivers by Toshiba are required to be installed for Windows 7 to be successful?
4. Is there a Bios update required for the machine to work on Windows 7?

Thanks.

Matt

Answer:Satellite P305-S8820 - Upgrade to Windows 7 Home Premium

Hi buddy,

> 1. Will I be able to perform a clean install by reformatting the disk?
If you buy an upgrade disk you can?t do a clean installation. With an upgrade disk you can only upgrade Vista to Windows 7.

> 2. Is there a utility from Toshiba, that will go find all the drivers for Windows 7?
No, you have to do this yourself.

> 3. Which drivers by Toshiba are required to be installed for Windows 7 to be successful?
All drivers that you need can be downloaded on Toshiba US page where your notebook model is listed:
http://www.csd.toshiba.com > Download > Laptops > Satellite > Satellite P305-S8820

> 4. Is there a Bios update required for the machine to work on Windows 7?
No, BIOS update has nothing to do with operating system and if everything is ok with your notebook don?t make a BIOS update. This is only important if you have a serious problem that can be solved with BIOS update.

I have a problem with a Satellite A210-103. After installation of Toshiba Value Added Package (Flash Cards Support Utility not available for A210), reboot, restarting Toshiba Flash Cards and pressing the FN key several times the problem still exists.

It must have other reasons why so many user have problems with the FN keys.

John

Answer:Re: Satellite P305-S8820 - FN key not working after clean install of Windows 7

Hello John

This with FN keys can be really problematic. On my Satellite A300 I had luck with FN functionality.
What you can try is to check if ?Flash card support utility? is available for your notebook model or maybe for A200.

Try to install it, restart notebook and check FN keys functionality again.

Hi,

I have a Toshiba Satellite P305-S8820. I recently did a clean install of Windows 7. I have loaded the Toshiba value added driver pack and the trackpad driver but still cannot get the trackpad or the FN key to work.

Any ideas?

Answer:Satellite P305-S8820 - FN key not working after clean install of Windows 7

Hi taxwiz,

I think the forum contains already hundreds of threads about this so why you don?t use the forum search?

Anyway, you need the latest version of Toshiba Value Added Package and Flash Cards Support Utility.
Try also restarting Toshiba Flash Cards (start > all programs > Toshiba) and press the FN keys several times.

Hi

I've a problem with my s955 (14 months old). It is not able to boot anymore. when switched on I can hear only cooling fan spinning up and down and nothing more. Last time it took almost half an hour to bypass this failure. When it's on it does not show any problem at all. When you switched off it's better praying. Now it seems gone. After an hour I cannot see any sign of life except cooling fan activity.

I went thru all the tricks mentioned in another Toshiba forum like power off, take out the battery, keep and hold the power button for at least 60 seconds. I even replaced the internal li-ion rtc battery but with no luck. Because it's not covered by guarantee anymore I opened it. No sign of burnt except a suspicious oxidization of some contacts.

I've contacted Toshiba Italy (even though this is a USA model) and I'm waiting for a possible answer next week. I ran out of possible solution except mobo replacement. Is there anybody around who did face the same issue? Could you please give me an help?
Thanks and best regards

Pyder

Answer:Satellite S955 won't boot - no POST and black screen

Hi, no news from Toshiba Italy but I've found a Toshiba authorized workshop that can possibly fix this problem. It seems that, beyond other speculations, the problem can be originated by the mainboard power microfuse (read this interesting reply by maxtek73 [http://forums.toshiba.com/t5/Batteries-and-Power/My-Toshiba-Satellite-Laptop-Will-Not-Turn-On/m-p/584008#M11147] at the end of the post). It seems reasonable. Actually, keyboard, dvd player, battery charge, hd and cooling fan are powered up by the mainboard; it seems that there is not enough current to pass initials tests before the POST. That could explain why the cooling fan is trying to spin up at max speed but it cannot. I?d remind that at power on, any IT equipment push the fans at max speed and then slow down at normal rate before going into POST process. I?ll have a talk with the workshop technician and I?ll keep you informed.
Best Regards

I have tried every known cure I could find on the internet to fix this issue, apart from trying to reflow the dual graphics chips that are onboard this machine, which in my mind is a design fault by Toshiba as the heat sink only covers one of the two Graphics Chips on this model of the Toshiba L850D, and to me this seems totally wrong due to heat transferrence and multiple issues I have come across with the Graphics Chips overheating from other manufactureres, even though they have heatsinks covering their graphics chips.

I've researched the internet for well over a week and, so far, nobody has provided an answer to anyone who is/was or had this issue, which seems to relate to other models as well.

I found a thread from January 2014 detailing this exact issue, but there was no answer provided to correct.
I'm not sure if this is allowed, but the relevant thread to this exact issue is provided : -

The actual model I have here is the Toshiba Satellite L850D, being model number PSKGEA-003001 and motherboard specific number is H000052650 WKC-51 Revision 2.1 or 7054D2745F87.

These seem to be so hard to find (or maybe should be extinct) even on eBay, so am wondering if it is a Toshiba FU that they no longer use Dual Graphics chips without a heat sink over both?

Have found similar style boards on eBay, being a H000051780 WKC29 and H000050830 WKC32 but all others seem to be back to one onboard Graphics or what appears to be on onboard Processor???.

Appreciate any feedback. Thank you. Daryl.

Answer:Satellite 2430-201 doesn't boot and black screen

Sounds like a hardware issue?

Try this workaround: Remove the battery and AC/DC adaptor. Wait one hour and then connect the battery and AC/DC adaptor again. Now try to start the notebook again. Maybe it works.

If not it could be mainboard or CPU malfunction? But this can be checked from an authorized service provider or you buy a new notebook with full warranty.

Hi. Today, I went to turn my laptop on, and all I got was a completely black screen, and I saw a suggestion on the interwebs to plug a separate monitor into its VGA port so that I could see whether there was a problem with the motherboard or it was just the screen, so I did that, and the monitor displayed everything perfectly fine and I was able to use my laptop through it, so at that point, it was obviously just a problem with the screen. So I tried a suggestion that I'd seen, of removing and replacing the battery, and switching it back on while holding shift and F8, so I did that, and then it all of a sudden didn't work at all, even through the separate monitor, and then after just over a minute, it switched off suddenly, making the same sound as it does if you switch it off with the power button. I tried removing and replacing the battery a few times, and it still did the exact same thing. Someone suggested to me that I remove the battery and try it just powered by the mains through the charger, so I did that and it was still exactly the same, it powered off after just over a minute, so it's not a problem with the battery. It's always on for the same amount of time before it turns off again, always just over a minute. Also, if the laptop is working on the inside, then judging by how long it always used to take to boot, it would definitely be on the logon screen by the time it spontaneously powers off. Personally, I doubt it's working on the inside.

Hello,
I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

All:

I recently bought a P305-S8842 with Windows Vista. A few days after purchase, I went to boot it up and this loud, smoke-detector beeping sound began emitting from my laptop.

When the system finally booted, it was as if a key was stuck!! Every icon the cursor went over starting launching. When I finally cleared that up and clicked on Internet Explorer, it was as if 20 or so pages opened.

Within the past couple of weeks, I removed the 200 GB primary HDD and upgraded to a Western Digital 320 GB hard drive. Things seemed to be fine until yesterday in which upon booting-up, the loud beeping sound began again.

Got a bar that said "Windows Loading Files" but the machine kept beeping until the start up was finished.
However, once again, anything the cursor was placed over started launching about 20 times.

It was as if there is a button stuck somewhere and I cannot find it. Still don't know what was causing this loud beeping sound upon start up (and re-booting). And yes, I would occassionally get the System Repair window as well.

Today I was able to reload everything from the Toshiba recovery disks and now the machine seems to be working fine.

Just wondering if anyone has experienced this situation.
Also, when the laptop was making the beeping noise, the screen would periodically flash as if the F2 or F12 button had been pressed.

Looks like I am good to go for now, just wondering what to do if it happens again. Kind of curious th... Read more

Hello to everyone

I got a Toshiba C850D-140 laptop, bought about one-two years ago. I decided to reinstall Windows 7 and I began the whole process. Everything was good, the "expanding windows files" bullet finished successfully and then the laptop restarted automatically. Then the problems started.

No Toshiba logo showed up, only an underscore at the upper left corner, non blinking, just laying there. After about two seconds the system restarted and the underscore showed up. This process loops forever. I can enter BIOS menu, I can enter boot list menu but the problem is that the laptop cannot boot from any device. Neither HDD, nor USB nor DVD. The DVD contains genuine Windows 7, working and tested on other PC's but the laptop refuses to boot from it.

Any ideas?
Thanks beforehands

Answer:Satellite C850D-104 - no HDD boot, no ODD boot, just black screen

From my knowledge the ?blinking underscore? means a HDD problem.
But you said, the underscore does not blink but its ?lying?.

In some cases this could mean an RAM malfunction. However this is just an idea.

Question: did you set the BIOS to default? In BIOS press F9 to get default settings and pressing F10 save the changes.

Is HDD listed on the first BIOS page (HDD name, size,)???
If not, this means that HDD is faulty.

I have a G50-70 Laptop and yesterday I wanted to install Windows 8.1 (official release downloaded from Microsoft website). Everything went well and the laptop started but there was no Wi-Fi option, so I restarted it and opened the BIOS options to check if the wireless is enabled. It was enabled but I decided to choose the Default options for the BIOS because I saw on a forum that this may help. Sadly, when the laptop restarted it just stayed black and the monitor started flashing lighter black color every 1-2 seconds and nothing else happened. That's why I figured that I should reset the BIOS by removing the CMOS battery for a minute, I didn't know that this is not possible on this model. There are other things that I tried after that: 1. Unplugged the adapter and removed the battery and tried resetting the BIOS by holding on the Start button for about 30 seconds. I started the laptop after that and after waiting for about 5 minutes the Lenovo logo came up and it gave me some errors about not being able to boot IPV4 and IPV6 and sometimes it showed "checking media".

Hello, just finished putting another system up. I ran into a problem tough, when I booted the computer for the first time, all I got was a black screen. No bios, no post beep...

The setup:
MSI p6n SLI V2
Core 2 Duo E8200 2.66GHZ 6mb L2, 45nm (not compatible?)
Sparkle 8800GT 512mb
2Gb G.Skill DDR2 800mhz

The PSU didn't have a 8 pin 12v connector which the mobo had, so I didn't connect it. I will roam around the local computers stores for the cable today and see if it helps (hopefully thats the problem).

I fear it was my mistake tough, with the CPU choise. I tought the CPU list on MSIs site was of all the compatible CPUs and didn't notice that it said "in testing" on the side... damn.
 

Answer:No post beep, black screen on first boot

You absolutely need the correctly configured power supply to work with a motherboard and video graphics card of that quality.
The MSI website and the Core 2 Duo webside will advise you on capatibility between the two.

Hi all,

Since a few weeks, my computer have this strange problem... When I turn it on several hours after the last use, the screen keeps getting black (even when it's turned on) and I hear no post error. I hear and see the hard drive and the DVD-ROM being powered on, the green light on the mobo is turned on and all the fans are running. My computer specs :

- Mobo Asus A7V8X-X
- CPU AMD Athlon XP 2600+
- 1 x 512Mb Kingston DDR333 memory
- Video card Asus GEForce TI4200
- Generic PowerSupply 350w
- DVD-Rom LG
- HD Western Digital 40Gb
- Modem USR 56K int.

Here's all the tests I've done :

- Disconnected and reconnected all power cables and data cables inside computer;
- removed and put back all cards (modem and video card), also the memory module;
- cleared CMOS
- Tested video card, memory and hard drive in another computer.. it worked well
- Replaced the PSU... same prob
- Removed all cards, the memory module and disconnected all power cables except the mobo... same prob, no post
- Reseated CPU... Nope.

Later, it worked with no reason and I was able to use it and turned it off the same day. The day after, the same issue occured after the first try. The first test I'v done was to push some warm air into the computer with a hairdryer (ask me why I though to this solution). Guess what?? It worked.

Answer:Computer won't boot - No post, black screen

It sounds like a heat problem to me, and it's possible that the warm air from the hair dryer was cooler than the CPU and cooled it down enough to restart. So, the question is, are you sure the computer is too cold to run? Use the computer with the case open, or try blowing air from a fan into the case and see if the same thing happens - because I think it's getting hot and shutting down.

I started using the yoga around Dec 2013. I started experience boot issues around Dec 2014 (it decides to break just as my warranty ends...). Since my warranty was over anyways I decided to just leave it as is, I finally had some free time today to take a look at it in more detail. It will sometimes boot into safe mode but most of the time all it does is sit with a black screen with the fans intermittently spinning faster. It's a cycle that repeats every couple seconds.At first I thought it might be a bios issue or something in the windows installation was corrupted. But I can't boot to the bios and when I attempted a reinstallation of windows from the few times it has booted to safe mode, it has always failed because of various errors. But because it was able to boot to safe mode all my data has been backed up (fortunately). I read in another post that some owners were experiencing a similar issue because they use an external monitor. I have my yoga attached to a external monitor most of the time when at home for the past year. I have tried all those function keys so I know screen brightness, switch to external display etc are not causing the problem. Since the yoga broke I have already purchased a replacement laptop (from a different manufacturer) but if I can still salvage it I would like to try.  Any help would be appreciated.

Your laptop has a recovery NOVO button. Shutdown the laptop and press that button and follow on-screen instructions.
 
Here is the User Guide -

Look at Page 25 for Recovery.
 
If recovery fails, then shutdown and do these steps before starting again.
1) Shutdown
2) Disconnect power supply
3) Press power button for 30-40 seconds
4) Reconnect power supply and press NOVO button again.

I have seen some similar problems like mine posted here, but I am not 100% sure how to proceed, so here it goes. This is on a Dell Latitude D620 laptop. I caught Palladium trying to install itself, so I did not want to let it finish. Taskmanager was already disabled and a shut down attempt resulted in a hang, so I held the power switch till it forced a power down. On reboot after that I attempted to boot to safe mode, but hitting F8 did not get me to the safe mode menu. All I get is the black screen with no text and the flashing cursor. Subsequent attempts to boot produce the same result. The only options I have are F2 and F12 both of which work fine. I can boot from a CD or an external floppy. I have a near identical laptop that I have been working on, but I want my programs. The hard drive from the problem computer works fine in an external housing, but not to boot. While I had it in the external housing I ran Malwarebytes to rid myself of the remnants of the Palladium. When I put it in the good computer I get the same results. When I put the good HD in the problem computer it boots fine, but with driver issues (I guess it's not 100% identical). I copied the MBR from the good HD with MBRtool, but it will not load the OS with that MBR, so I reloaded the backed-up MBR. I also tried the Windows recovery console fixMBR. It also didn't let the OS boot. I started to do a Repair Install, but I quit at the HD partition page. It seems the instructions on MS&... Read more

I was trying to get into Safe Mode in Windows 10, and since I had not done so in a while I tried using the F8 key on boot. Instead of going to the Windows recovery screen (which I realize now is not accessed with F8), the Dell logo appeared with a blue progress bar underneath, but no text was present. After a couple seconds, the computer shut off. Since then, the screen backlight does not turn on and there is no display output, even from HDMI.
Here is what I have done so far to troubleshoot:

Disconnected battery/unplugged AC adapter, then powered on
Unplugged CMOS battery, powered on/off, plugged CMOS battery back in
Tried fn+power
Tried D+power (this did turn on the backlight and flash colors, but only this)
Held down power button for 30 seconds to turn on and off
Tried the BIOS recovery method (ctrl+esc with BIOS USB disk inserted)
Unplugged NVMe SSD and powered on
Powered on, then tapped F2 or F12 repeatedly to trigger BIOS configuration screen
and multiple combinations of the above

My BIOS has also been upgraded to the latest version as of a couple weeks ago. In all cases except D+power, the screen did not turn on, nor did the keyboard backlight (including caps lock). While powered on, if I pressed the power button, the fans would spin up for a few seconds and then shut down.
I called Dell support who had me try a few of the troubleshooting methods above, which again did not work. He came to the conclusion that the motherboard was dead (a "mechanical failure&q... Read more

I recently upgraded some of the hardware on my laptop (keyboard, hinges, memory), and laptop was working like a charm. The very next morning (laptop stays on at all times), the screen had gone black and the computer could not be rebooted. I do not know if the system did an automatic update overnight before the mysterious black screen appeared, but it is possible. Failure occurred on January 13, if that helps.

When I try to boot, I get a Dell splash screen and a successful POST, but at the point where it should hand off to the OS the screen goes black -- no Windows logo or hard drive activity.

I have tried replacing the hard drive, including a fresh installation of XPSP2 from the Dell CD. Drive formatted successfully and copied over all files, then had disk read error on restart. I have purchased a USB connector for the hard drive and was able to read and backup original drive using a different computer. New drive also appears fine (though it is 320GB and system only recognizes it as 137GB). Tried repartitioning new drive with 120GB partition (using other computer), booted from WinXPSP2 CD, and black screen appears after "Windows is inspecting your hardware".

I have tried replacing the boot.ini, ntdetect, and ntldr files on the original hard drive and tried using a boot CD (laptop does not have a floppy drive), but still get the same black screen.

I have tried a repair installation on the original hard drive. Windows files copy over with no problem, black screen ... Read more

Answer:Solved: XP Pro fails to boot (black screen) after successful POST

What model Dell is it?

Create 3 partitions on the drive, all of them under 137gb, then try to install XP to the first partition.

If it is an IDE drive, be sure it is jumpered CS (cable select) when you put it in the Dell.

MY 11 year old HP Media Center m7330n worked fine yesterday and shut down normally after playing a DVD on statistics. This morning I tried starting it and  I observed the black screen with no evidence of the POST starting (pressing the computer ON button the monitor shows the 'no signal' message for a second or two and then the screen goes black/blank), no little arrow of the cursor on screen, a constant beeping starts with about one second between beeps.
 
The following tests and observations were made:
1.  CMOS battery measured 3v.
2. Power supply tested OK with a battery tester (after all connections from the supply disconnected from mother board and other computer components).  Green light on power supply ON when connected to 115vac.
3. Monitor tested on another computer and OK. 
4. When computer turned on the cooling fans run fine.
5. Hard Drive ruins when power on.
6. Not sure if this important  :  but think I had to pull the ac plug to turn computer off all the time ( or maybe occasionally)occasionally while doing some of the tests.
 
I have no idea what the steady beeping means/indicates. 
 
A search of this forum for similar conditions seems to indicate the motherboard has failed.  I'm hoping there are some more tests that can be done before coming to this conclusion.
 
Any suggestions/comments greatly appreciated.

Answer:Black Screen, no Post, no boot, no cursor, with steady beeping

Depending on BIOS, a single beep repeated can be a RAM fault. The simplest check would be to remove the memory modules and power up to see if the beep code changes.

Hey,

It seems that the water has damged your notebook or some parts at least. In worst case you need a lot of new hardware parts but I think only an authorized service provider can help you to diagnose this problem.

On the Toshiba website you can search for them:

Contact them and ask for help. They will help you as best as possible. :)

Hi. I have recently reinstalled Windows 10 on my Desktop PC.
The PC is not booting to windows. Instead it displays a solid underscore in the top left corner of the screen and does nothing. No opportunity to enter BIOS, even. Nothing except the underscore.
If I turn the PC off at the mains and leave it for 30 seconds or so the PC will then boot to Windows fine, so I wonder if there is something stored in non volatile memory somewhere that is causing a problem. I can't think what it might be though.
The problem started when I reinstalled Windows. The first time I had to cancel the installation and when the computer rebooted, the underscore appeared. I managed to get Windows installed by powering down at the mains and assumed that the problem would correct itself after formatting my C drive. But it hasn't. It currently happens after every time I restart the PC.
Does anybody have any suggestions to what the problem might be?
Thanks for reading

When my TECRA A8 starts I get a black screen (Invalid Boot.INI file Booting from c:\Windows).
Why is this happening?

Updating the BIOS did not solve it.

Answer:Tecra A8 doesn't boot - I get a black screen

Hi!

I think a BIOS update can?t solve this problem because there is something wrong with the Windows installation and the BIOS has nothing to do with this. So don?t mix these different things.

In your case I would use the Toshiba recovery disk to reinstall Windows. This should solve the problem because the disk contains the factory settings. After this you should be able to boot into Windows again.

Hi,

I'm hoping any knowledgeable people here might be able to help me, please.

After a failed attempt to install Comodo Firewall (followed by me uninstalling it), my computer will no longer boot. It starts to load windows, and gets to the point of a black screen with a white cursor (just before the desktop is loaded), then tells me:

* lsass.exe failed to initialize properly

* services.exe failed to initialize properly

After each of these, I click OK. Then I'm left with a black screen.

I've tried Safe Mode, but I get the same two errors. I believe that System Restore was disabled (I can't believe I left it off after the last virus cleaning episode!).

Hi All,

I have a Windows 7 Pro x64 which has been running for a many months without any issues.

Three days ago I restarted the machine and Windows 7 didn't start anymore. I have spent a lot of time investigating it and could not find anything wrong with the boot loader or the file system where the OS is.

So the boot loader works, I have also replaced it just in case but nothing changed. I can go into the boot loader menu and chose the Windows 7 entry but then the black screen which says "Starting Windows" comes and nothing else happens.

Note that the computer doesn't hang, it simply gets stuck at some point and doesn't do anything else. The HDD LED stays on from this point forward and that is it, if I press ctrl+alt+del it restarts and if it were completely frozen it wouldn't.

So here is what I don't believe is causing the problem:

This Windows 7 runs on a pair of drives in RADI1 so it cannot be a problem with the drives. I have run checks just to be sure and couldn't find anything, no file system issues or bad blocks.

The raid controller is not reporting any issues with the drives.

I have booted with the windows install cd and tried to repair it many times but the auto repair says it could not repair it, other times it tells me that no issue was found.

The boot manager is working fine, I have replaced it just in case using bootrec /fixmbr and /fixboot and also bootsect /nt60 all.

Hello everyone. First of all, I would like to start off by saying I love your forum here. I have used it many, many, many times in order to resolve a problem I encountered here in our computer repair shop, so much props goes to you guys.
 
We have a customer's computer running Windows XP Professional that will not boot. After the Compaq splash screen, it simply hangs at an all black screen with a white blinking cursor in the upper left hand corner of the screen. I have already searched your forums as well as poured over Google searches and tried various things. The things I have already tried to no avail are:
 
1. Boot into Recovery Console from Windows XP Pro CD and fixboot/fixmbr
2. Replace RAM with new RAM.
3. Replace NTLDR file from a working Windows XP Pro machine
4. chkdsk /r
5. Used a guide here on your forums for using xPUD with mbr.bin on a USB. Not sure what was supposed to of happened, because nothing did after I followed all the steps. Completely unchanged.
6. I have also tried booting into Safe Mode, which also does nothing.
 
Finally, out of my own frusteration, I booted the computer to Hirem's Boot CD and used it's "Fix NTLDR Is Missing" tool using the first option out of 10 possible fixes and wham! Boots Windows first try. However, upon restart of the customer's computer I am again greeted with the black screen and a blinking cursor. I must use Hirem's Boot CD to boot Windows each time.

Being pretty familiar and having exchanged parts before, I felt confident enough to put together one from scratch. Everything (except the case, which was in pretty good condition except some scratches) was brand new. And everything worked great from the first boot up - I got windows 7 installed, etc, no problem. However, when I went to restart after installing some drivers, it did shut down the system and started back up... but it didn't boot up at all. The motherboard never makes beeps, and this time was no different... but the motherboard green light was on.

After this short period of time connect both parts and try to boot up the notebook.

If it doesn?t help the chances are that your hardware is faulty. Like the other guys said, it could be a motherboard fault or something different like CPU, memory modules.
I can speculate about the malfunction.

I think you have not many choices. In your case you should contact the ASP in your country for a notebook check.

ok.. my wifes L850D was having problems with black screening on boot up after the toshiba screen.

I ran a few different utilities including a reset.... this all started about 3 weeks after the win 8.1 upgrade.

Rang tech support who nicely informed me that because we put 8.1 on it it voided the warrenty. (nice guys btw)
So refused to help.

So went and reloaded Win 8 from my DeII, just to see if it was a problem with hardware of software.
(yes i know but it was to be only temp).

It booted fine, sat there for ages without a problem.
It wasnt until i downloaded the toshiba drivers, (yes the right ones) did a reboot and hey presto; black screen again.

That would kinda imply its a problem with the toshiba drivers?

Ok so the wife decided screw it, put Win 7 on it.
Rebooted with the disk in. sat and sat. google finally informed me i had to disable secureboot, and put uefi to csm.

Ok fine, went into the bios, disabled secure boot, changed uefi to csm and reboot.
Now i get nothing; screen wont come on at all, fan starts, cd rom kicks over and nothing, shuts down instantly if i push the power button.

I've pulled the battery out, external and internal, let it sit for a half hour and still the same thing.

Any ideas???

Answer:Satellite L850D does not boot up - black screen

The whole story is for me a bit confused so let me start from the beginning with some basic stuff.
In your posting you didn?t write which model do you have exactly (L850D-xxx) and I cannot check notebook specification but I presume this notebook was delivered with preinstalled OS, probably Win8.
Notebook with ?factory settings? has preinstalled OS that includes all necessary drivers, tools and utilities. One of them is ?Toshiba recovery media creator?. Using this tool you can create recovery media (DVD or USB) and use it to reinstall original OS if there s some problem and HDD recovery doesn't work.
Best option now would be to use such media and install original recovery image. Have you created this recovery media?

Generally speaking when you by new notebook you are not obliged to use original OS. You can install whatever you want and it has nothing with warranty. You can install any OS, especially all supported operating systems. So I don't understand how you could get such info from technical support.

Anyway, try please to connect your notebook to AC power supply and start notebook again. What happen exactly? Can you see ?Toshiba welcome screen?? Try to press F12 several times. Any reaction there?

Issue:
Pressing the power button to power on the computer for a full boot, the power led switches on but screen stays dark (even no illumination). The "Satellite" led-logo on the lower left corner of the chassis stays off while the HDD led makes a quick single blink; the DVD activity led (on device) stays always on even without any CD inserted, pressing the eject switch does nothing (tray is locked) and no activity noises.
No boot logo screen (display stays dark and off), no beeps, no HDD or DVD activities, keyboard seems to not working (any combinations that should switch on a led, such as capslock, numlock, etc., does nothing), the fan works.

What I already (unsuccesfully) tried:
- Unlock the tray, insert the rescue CD and power on
- Remove the main battery and power on with AC adapter only
- Insert a bootable USB stick/external HDD

The computer was working as expected the day before and it has not suffered any kind of shock. What described is the situation I faced with when I turned it on the next time (just 24 hours later).

What could be gone wrong?
Thank you.

Well, looks like hardware problem; maybe memory issue or something serious with motherboard or CPU. It?s really difficult to say what could cause this.
You can try to check the RAM modules.
Try to boot using one single module? maybe it helps? otherwise I?m afraid you will need a help from Toshiba ASP technicians?

This is very useful info?
I think the issue is related to the FL inverter?
The FL-inverter is a small part which controls the display backlight.
If this part starts to malfunction then you would see everything like behind a thick fog?

In my opinion the FL inverter should be checked and replaced if necessary?
For that you have to get in contact with an local service technician?

Greets & happy new year!

I have a U200-115, I downloaded a BIOS upgrade from toshiba and installed it according to their instructions. Since the upgrade my laptop won't boot, All I get is a black sreen with a beeping sound and an orange light flashing.

Any Ideas ?

Answer:Black Screen at boot with a Satellite U200-115

your bios upgrade failed. your only hope is to contact toshiba and have it serviced. there are some bios recovery options you can try. google "toshiba bios recovery" or "toshiba failed bios flash" and see what you can find, otherwise contact toshiba.

Hello

I hope you can help me.

I have a Satellite L50-A-170 for about a month.
Today, after 3 days of inactivity I tried to turn it back on but you hear the noise of the optical drive and the fan noise but the screen remains black.

It seems to me that you do not even turn on the screen backlight. I wanted to try to disconnect the battery for a few minutes but it is integrated.

You have an idea on how I can proceed?
I have great need of the PC and the data!

Thank you in advance!

Because of that, there is an *Reset Switch* placed at the bottom of the unit.

Hello

I have a problem on my PC (Satellite C855D-124) more precisely was playing a game and stopped out of nowhere I could not do any command then turned it off Button.

But as I returned the call and turned those lights appeared as the load appears as a small light and also appears on ta but then nothing appeared on the monitor, no warning message or error ...

So it connects but does not appear anything and I would like to know if you can help with any tips about what happened and what I do or what I myself can do ....

Sorry for errors but i do this on google translator...

Answer:Satellite C855D-124 does not boot up - black screen

Hello Adrian

For me it is not easy to understand your problem but all you can do at the moment is to restart your notebook, and check if basic operations work properly. Try to restart it several times to see what will happen.

When notebook starts can you see Toshiba welcome screen?
Is there usual HDD activity at start-up?

Hi all,

I was using my computer yesterday and it started freezing all of a sudden, I held the power button and turned it off. Today I am unable to boot it up.

I have two options:
1. Repair Windows
2. Start Windows normally

If I select option 1, it loads the Windows files and then gets to a Black Screen with nothing on it where I can move the mouse. If I select option 2, it comes to the "Loading Windows Screen" and remains there.

The black screen occurs if I try and boot in Safe Mode, repair windows, or boot from another version of Windows 7 I have on CD.

Please help me on what to do. I have important data that I have not backed up so I will only reset to factory settings as last resort.

How can I access my data? Should I remove the hard drive and put it in another computer?

All help appreciated.

Answer:Satellite A500 - Black screen when I boot

Hello

> Should I remove the hard drive and put it in another computer?
If you have important data on your computer you should do this to make a backup of these files. So I would recommend buying an external HDD case where you can put in the HDD to backup all files on another computer.
But I think I will never understand why some people don?t have a backup. In my opinion it?s the most important thing and always be done from time to time.

Anyway, it seems your Windows installation is muddled up and therefore it?s necessary to restore factory settings from Toshiba recovery disk but it will delete everything on HDD.

Hi
I read a thread that is seeking help for the L50-A's black screen start up problem. In the thread, the problem was solved.(https://forum.toshiba.eu/showthread....op-won-t-start)
I have the same problem, but the difference is that mine is a L50-B model and I can't find the shutdown switch on the back of my laptop.
I bought this laptop last September, it was all fine until last months. Every time when I switch on the computer, it took a very long time to pass the black screen. From this week, it even didn't turn on at all. But the power light is on, the fan is working, the wi-fi light is on, and the CD rom can be opened.... but the screen is totally black.
I followed some instructions online and took off the battery, plug on the power supply and tried to turn on again, but it didn't work.
Can anyone estimate what is the problem and how can I fix it?
below is a description I copied from the existing thread.

It was connected to the charger with the charging light on but wouldn't power up. When I press the power button, the little orange light ring around the button will light up and so will all the LED lights on the front of the laptop, as well as I can hear the fan and other components working, however the screen will remain blank.

After 15 months my Toshiba A200 seems to have given up the ghost.

I tried to switch it on today and although the blue stand-by LED came on and the orange light on the disk drive there were no other signs of life.
I tried and tried but it just would not boot and the screen did nothing but remain blank.
I tried taking the battery out for more than 30mins, pressing F4 - but nothing.
I have no memory cards inserted or additional hardware such as a webcam. Everything has worked fine before now.

I am not very technical so of you do know how to help then please explain as simply as possible.

I really appreciate any help you may be able to offer!

Answer:Satellite A200-1M4 does not boot and black screen

> I tried taking the battery out for more than 30mins, pressing F4 - but nothing.
Why you try to press F4?
However, remove the battery, disconnect the AC/DC adaptor, wait up to one hour and then connect the battery and AC/DC adaptor again.

If the notebook doesn?t boot I think the mainboard must be replaced. Ask your local ASP for help. They can order and exchange the mainboard.

Laptop will not boot. Power light turns on. Fan spins up for a few seconds then stops. HDD spins up. No display. No POST.
Striped it down. Nothing appears out of the ordinary.
Searched the web. This appears to be a common problem with Toshiba laptops.
Common fix is supposed to be the power button held for a minute or so with battery out. This did not work in this case.

Something like this can happen on any notebook so it has nothing directly with Toshiba or any other notebook manufacturer.
Sometimes such behaviour can happen after not successfully BIOS update. Have you may be done BIOS update or anything else that can be responsible for this?

I cannot say for sure but somehow I think BIOS is screwed up.

Help will be appreciated.

Answer:Satellite L300-1EF - Black screen on boot

Hello

Have you tested an external monitor on the notebook? So you can determine if the screen is black due a faulty internal monitor or mainboard/graphic card.
Check this!!!

But I think you will need help from a notebook technician. It could be a hardware issue and notebook disassembling isn?t so easy and should only be done from professional technicians.

Hi all,

Here's the story:

I played poker yesterday with my laptop and suddenly the screen freeze. i.e. No more mouse/keyboard, date/time freezed.
There's no battery in my laptop so i unplugged the power supply.

When i plugged it in, i pushed the power button. The fan came on, the blue leds of Power cord, Power came in. The Hard disk led start blinking. But the screen was black ! No backlight at all. The computer don't seemed to boot as the hard disk light wasn't blinking anymore after 5 sec. or so.

I've done theses steps 3-4 times. No results.

I managed to check the memory, swapped the 2x 2gig sodimm with 2x1gig sodimm i've got, same effect, the screen stay black. Rollback on this...

Waited 5 minutes without battery/power cord. Everything booted right.

I ran a memory diagnostic tool for 24h after that, no problem at all.
I've already got the last bios version.

I found in this forum the solution to Remove Power, let sit for 30 minutes and the black scrren is gone. But i don't think it is a long term solution.

I'm afraid about this problem. (Black Screen) since i understand it is a hardware fault ?
Do someone know more about this kind of issue?

Answer:Satellite A200-TJ5 ---> Black Screen on boot

Hmmm?. Possibly it?s an hardware issue but as you know it?s really not easy to provide any suggestions without any detailed notebook /hardware checks.

So if you want, you can contact the nearest ASP in your country and can ask for the notebook diagnostic test.

I just got this computer a couple of days ago and all is going well except I am bonkers over the various options to sleep, shut down and revive.

I am set so it never goes down, as I want the screen on to monitor my navigation for long periods of time, in the power connected mode.

On the lid options I have it set to hibernate.

But here is where the fun begins. I has a mind of its own and does not always do the same.

For instance, if I lift the lid sometimes its dead and nothing will revive it.
The only option is to hold down the power button for several secs and get a cold shut down. Then press the button again and it boots in the previous state of windows.

Even stranger last night I shut down for the night with the
Start -> Shutdown and it shut down fine.
But came by in a couple of minutes and it had rebooted.

Did this a couple of times.
I took out the power cord and then it did not reboot.

I am trying to understand things before making a big case on phone so any help would be appreciated.

Answer:Satellite P305-S8838 doesn't wake up from hibernation & reboots sometimes

I have found the gremlin as for the frequent restarts from hiberation. In the BIOS there is an item, Wake up on LAN, or something similar and I disabled it.

So not it does not reboot and just stays in hiberation.

But the only way I can wake it up is to hold the power button done for several seconds until all the lights go out and then touch the power button again. It goes to Restarting Windows and comes back.

I felt that holding the button down several seconds was a cold shutdown and might be damaging things as in previous windows versions.

Is this now an acceptable procedure with Vista?

I'm having some trouble with my year old Satellite C650. Basically, when I go to switch it on it just...won't. The power light on the front of the laptop comes on, and the fan starts whirring (only to stop a few seconds later) but there's no change whatsoever in the screen. I've tried taking out the battery, restarting, plugging it in, unplugging it - basically everything I can think of, but nothing's made a difference.

My advice would be talking to an Toshiba service provider in your country who would check the parts.
Your notebook does not seem to be old so maybe warranty is still valid and the fix could be done free of charge.

Hello everyone,

My Toshiba Satellite A200 notebook is not working anymore, so everything started when I was playing a game, suddenly, the screen turned blue with some tiny text written on it. I had to hold the power button a few seconds to close it because nothing was happening on the computer. I then pressed the power button to open it. Everthing was going well, until the welcome screen. At this part, it was written "Welcome" but the Vista loading circle left of it wasn't turning.

After a few seconds, I decided to close the computer again, so I did hold the power button so the computer closed. Here is the problem : I tried to reopen it, but the screen stayed black. Nothing was happening. The power light was blue, but not any computer activity. So I let it like that a few minutes then closed it and tried again, but the same thing happened. I tried to disassemble it and noticed one of the two memory card wasn't fully in its slot. I fixed it, but it didn't fix the problem.

I also tried to plug another screen on it, but that one was also black. So I put back the screen on its computer and tried to boot my laptop and it worked. It was booting, but the first problem came back, the Welcome screen was frooze there. So yes I did close it again and then the same thing happened, the screen stayed black.

Answer:Satellite A200 screen stays black when trying to boot

Finally, it doesn't work. I don't know why but my computer did start up after the 30 minutes, but now it's not working anymore. It just won't startup like I said later, with a black screen.

The computer did work for about half an hour. I mean, I managed to start it up but after executing a program, it just froze and I had to hold the power button to restart it. I did it about 3 or 4 times, then it simply did the black screen again. I think the problem is my processor, maybe it's damaged or something, could it be possible?

Because I see that the processor isn't working when I try to start it up.

So let's say it's damaged, would that be the symptoms of my computer?
And if it's the processor, the only way to fix it is to send it to a reparator or something, because I don't feel like it, I'd rather do it myself.

But right now, my computer is simply not booting, like I said in my previous post.

Thanks in advance,

Hello Guys,

I've got a strange problem with a Satellite M60-128.
When I start the notebook there are some problems:

* sometimes the screen remains black (no Toshiba logo) and the notebook doens't start
* sometimes the notebook starts normally (when it hanged before and I switched it off with the power button)
* sometimes the Toshiba-logo is visible but stops there

I also have sometimes a problem that the USB-ports doesn't work. When I reboot, It works fine. When the USB-ports fail, there is a warning in computer devices.

I've done a BIOS-update (v1.60) but the problem remains.

I noticed this: when the notebook doens't start and I "click" on the toutchpad's right button the Toshiba logo is visible and the notebook starts.

Anyone familiar with this problem or does some knows a solution? Thanks in advantage.

Andy

Very strange issue? usually the notebook should starts automatically without pressing the touchpad button. For me this makes no sense and it looks a little bit like a motherboard issue?
What do you think about this?

Did you try to reinstall the OS with the delivered Toshiba recovery CD?
Maybe you should do it to ensure that this is not a software issue?

I have a Toshiba Satellite A100-011, which is almost 5-6 years old. It suddenly started to behave abnormal.

First, I started to get some black screen for 1-2 sec when it was running. The screen was on and off from time to time.

After couple of days, I could not started up my windows xp sp3 operating system. I tried to start in safe mode with networking to check if I got some spy, virus or something. I have run avast, hijact this, ad aware and some more but could not find anything at all.

Later on, I decided to format my laptop with an xp professional but this time I can not see any think happening more than fun running and a black screen. I just got a black screen at the beginning and it does not boot.

I connected it to a TV screen and there I could started up. I re-installed all drivers and formatted it but all I got is a black screen on my laptop at the very beginning.

What should I do now? Do you think I have a HW problem with my screen or a driver problem with nvidia geforce go 7600? Maybe I am missing something?

Thanks in advance for all answers.

Answer:Re: Satellite A100-011 does not boot and a black screen at the start

If you can see the pic on the TV there must be some problem with notebook?s display. Either is there some connection problem or display itself.

Do you want to repair it on your own? Can you disassemble the notebook?
I mean if you have no experience with this stuff you should ask for professional help.

I have a major problem. My Toshiba Satellite 1900, WINXP Home edition, (not SP2 updated) P4,2.0Ghz, 256mb RAM, won't boot up.
I was running Norton Sys works - speed disk to defrag the HD. The screen was blank because the power setting I have switches it off after 10mins of no input.

My son passed the laptop with the (lid)open as he called it, and thought I forgot to close it as the screen was blank, and of course the laptop shut down. When I reopened the (lid) screen again it would not display and the system had no POST beeps. I tried to boot from a Toshiba recovery CD - nothing, then a recovery floppy - no joy - I then tried to boot from a WINXP boot CD - again no joy. A friend gave me a loan of his SPINRITE v6.0 disc to boot from as he says it has its own O/S - again not joy. The battery and power adapters are all ok we tested them with a multi-meter.

One further note is that I have GOBACK v3 installed but due to the fact the laptop wont boot I cannot recover the last good point. I also believe that as I was running a defrag program when this accident occurred the restore points will be cleared from memory.

At this point I am stumped. I have some work on the laptop (Excel Files) that I need to access. Any suggestions/help would be appreciated.

My last resort after this forum is to go to PC World clinic which I have never resorted in the past. The laptop was bought in PC World and I never had a problem with it

I?m afraid the BIOS update procedure failed and therefore the ROM chip has not been updated as it should. This is the reason why the notebook cannot boot up properly.

I think it?s necessary to reflash the BIOS ROM module again but this can be done only using an crisis BIOS procedure.
As far as I know this can be done only by ASP because there is no traditional BIOS version for download.

I know there're several postings here reporting how the screen is black at startup. I think my problem is similar, but I need to give some more specifics.

About a year ago, a friend of mine gave me his old laptop, a Satellite 1800-814. I basically use it as a typewriter, and to check my email. It never could run on battery only, longer than for a couple of seconds, but I've always used it with the power cable connected, no problems. At times, it wouldn't start up, and I had to unplug the power cable for a while to get it going.

I was visiting someone, and wanted to connect to the Internet. They had this USB wireless modem, which I plugged in to my Toshiba. During the installation, the PC froze, and I had to reboot it by pushing down the power button for a while. It did reboot, but stalled. I rebooted again, sometimes got it working, sometimes not, and eventually, it went into its current state: With the power cord connected, it'll start, I'll hear the processor fan (or whatever that is) working, and the battery and power lights will be green at the bottom of the keyboard.

The screen, however, is black, it doesn't make any sounds, and the caps and insert key indicator lights are not reacting to anything -- they're permanently off.

What's up here? I tried removing the battery, give it some time and then reinserting it, but to no avail. I also tried booting it up with the USB modem plugged in, no luck there either. Do I need to make an appointment with the PC Doc, o... Read more

Toshiba Satellite C50-A-19T

I'm posting this as last resort. I see a huge amount of threads on these forums with 0 replies.... and none from any Toshiba techs.... so my chances of getting a solution seem very slim. Nevertheless I must try. If nothing else someone with a similar problem can see what I've tried and they can use it to try and fix their own.

The laptop will not boot when the battery is connected. The Power button will light and the Hard drive LED will light, but the screen stays black and shows no display. If I take the battery out and run from the AC adapter then it will boot and I can use the laptop, but this defeats the purpose of buying a laptop.

The problem existed on Windows 8. I have upgraded to Windows 10 but this didn't solve the problem. I then read that restoring to the factory default might fix it, so I've run a complete Factory Reset. This did not fix the problem. I have gone back to Windows 10 and downloaded/installed all the drivers.

So I need to boot the laptop without the battery. If I do this and then plug the battery in, the charging LED lights solid orange. It will stay like this for about 10-15 minutes and then change to a slow blinking orange. At no time does the battery show in the System Tray. The icon always says "Battery Not Detected".

Hello Experts,

I have Toshiba Satellite L650D which is acting strange since last few days.
The problem is that it doesnt power up generally.

Contrary to other similar problems on the web, it doesnt go to Toshiba boot screen.
Screen stays black! when I first try to power up, I only hear few sounds from DVD drive nothing else.
When I try to hard reset it by holding power button for 30 seconds or more, I hear hard disk (or power supply) sound but nothing happens.

I randomly do hard reset with power wihout battery, with battery without power and without battery without power. After many attempts it suddenly starts normally and works fine afterwards. it is appening since last thre days. everytime i shutdown, i have to do this

. I am writing this from the same laptop. If I shut it down now, it will take me another 30 minutes and many random combinations of hard reset to make it work.

Someone suggested that power output of the adapter might be a problem. can we check voltage output without using fancy electrical devices?

Please help. i cant afford new laptop right now.

I?m afraid there is something wrong with the motherboard or part connected to the mobo like RAM modules.
If you did not check the RAM modules in the past, I would recommend doing this since faulty RAM could affect the notebook functionality. Furthermore the RAM modules are not very expensive, so it?s worth to check these parts.

But please don?t understand me wrong; I don?t say there is a problem with RAM. I said, this could be the troublemaker. So please don?t be disappointed if this workaround would not help.

Answer:Satellite L500-1XL - Won't boot and screen stays black

Hi gazzdowzell,

If your notebook doesn?t boot it seems to be a hardware malfunction? It could be everything, mainboard, BIOS, CPU, etc. and it?s hard to say what is exactly wrong.

First of all I would try this:
[Which steps should be followed if your Toshiba notebook doesn't start? |http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=21]

If it doesn?t work you should contact an authorized service provider in your country. If your notebook is under warranty, the repair is for free.
Furthermore if you remove the RAM and the notebook doesn?t beep, it seems to be another problem. If the RAM module would be faulty and you have removed it, the computer would beep.

Good luck!

My Satellite M50-130 does not start up correctly. When switching it on, it goes to a black MS-DOS screen saying "We apologize for the inconvenience, but Windows did not start successfully. A recent hardware or software change might have caused this." It offers me different start up modes: Safe Mode, with Networking and with Command Prompt; Last Known Good Configuration; and Start Windows Normally.

I tried all 5 options, the start up gets as far as the Toshiba screen, but then with all options it returns to the initial screen offering the 5 start up modes. Same thing happens when switching laptop off and on again.

The only recent software change I made was an update of Norton AntiVirus/Internet Security, and I suspect Norton is at least part of my problem, see the history below. I know this is the Toshiba help site, but I tried Norton so many times unsuccessfully, I've given up. Plus, I'm no expert at all, so I can't be sure this is really the source of all my sorrows. Any advice welcome!

My laptop's performance deteriorated badly over the last couple of months. It's extremely slow, and cleaning it from malware and general junk doesn't help. It started right after I renewed the Norton license last year and upgraded to the 2007 version. The worst slowdowns are always connected to Norton's live upgrade programmes coming on. I deactivated the live upgrade, but the programmes still come up, and I can't shut them down, a popup tells me they are protected.

Answer:Satellite M50 doesn't boot, returns to screen with different start modes

Hi there,

I think the only way to make your system running properly again is to restore it with the shipped recovery cdrom. Just manage it to backup your data from your harddrive (the best way would be to put the HDD from your machine into an USB-HDD-case and copy the important data to another computer) and then to wipe the system completely off you hdd.

After this, the system should run again...

Model: satellite C650

Operating System: windows 7 home premium

Problem: when I try to turn the computer on I see the Toshiba screen and then a black screen with a underscore that flashes a few times then stops, and the computer is stuck that way. The fan appears to be working. I can't go into safe mode or any boot options even though I press f8 or f12 nonstop.

Last time I booted in I was stuck on log in screen but touch pad and keyboard wasn't working and I couldn't shut down. After I force shut down and try to restart it gets stuck like this. No beeps or anything.

Any help would be appreciated.
Thanks

Hello, I have a Satellite A300D-13A and the problem is, when i try to start the notebook mostly it tries to boot from the hard disk and from the DVD drive but then it just shuts down and immediatly starts again to do the same. This happens 4 or 5 times. After that it is seems like it finally boots but the only thing i see is a black screen. And the keyboard does not work either.

If i try it a few times with shutting down by pressing the power button (you know which I mean), I manage that it starts normally (but such a situation is still anoying). By the way, it seems like it happens only, when I haven't used the notebook for a while. So maybe it has something to do with the temperature. But 's more or less 20?C in my room.

In the Bios I have change the order of booting sources (I can't change there much more)

I'm grateful for any kind of help.
Thanks for your cooments in advance

Answer:Re: Satellite A300D-13A: Start problems - does not boot or only black screen

Hi

The issue could be related to the software but also to the hardware problem.
But first of all we should check if it?s a software issue.

You are using the original preinstalled OS by Toshiba. Is it right?
As far as I know the newer notebook series are equipped with the HDD recovery option.
In this case the Toshiba Recovery DVD was not delivered together with the notebook but there is an option to create one.
HDD recovery option can be used to reinstall and to refresh the operating system.
I would recommend repairing the OS and to reinstall it again pressing the F8 button. The advanced boot menu should appear and then you should choose ?Repair your Computer?.

This option will start the recovery procedure and the OS would reinstall again.
Please check if a new installation will improve the situation with the notebook.
Additionally it would be advisable to update the BIOS if a newer BIOS version is available on the Toshibas European driver page.

If all this suggestion will not help you then the whole notebooks hardware should be checked by a local ASP.

the screen whilst starting up is black with the mouse cursor showing white - but wont start up

the computer is only 3 months old with windows 8

please help me

thanks

Answer:Satellite C850 does not boot up - black screen with while mouse cursor

You mean an blinking/flashing underscore in the left upper corner?
This is mostly an indicator for HDD malfunction.

In your case I recommend contacting the Toshiba authorized service provider because the notebook is 3 month old. In this case the warranty is still valid and you should get it fixed free of charge.

Hi,
Sorry first time poster. I wasn't too sure whether to post to the Windows forums or hardware forums. From what I can see, this seems like a hardware issue of some sort.

The problem I have is that during bootup my PC goes through all the normal things. It detects my CPU, detects RAM etc. gives me nice BIOS Post messages that appear normal and then goes to a black screen. It will then sit there for 50 seconds (i've timed this twice) and then proceed to go to the windows XP startup screen (which takes about another 10-20 seconds to load up windows).

I've attempted to log the bootups by using the Windows Boot logger (by pressing F8 before windows boots). The ntbtlog.txt file isn't very descriptive, and only lists that a whole lot of drivers have been loaded, and some that haven't (it doesn't list any errors).

I've also tried using BootVis to analyse the bootup. I found this a little hard to decode the information it gave me, but there doesn't seem to be anything untoward happening.
The last boot logger I tried was bootLog XP (by greatis software). According to bootlog XP, windows is only taking 19 seconds to load up.

Can anyone suggest any other ways to analyse the boot sequence and discover where my computer is stalling?

(specs are below.)

Thanks in advance,

Matt

Hi I have 3 years old Toshiba L300D.
1 year back I upgraded vista to windows 7 Home premium.

3 days back I had problem - my starting windows page was hanged and was not proceeding forward, also All types of safe mode was getting stuck on classpnp.sys.

After reading many forums I booted with USB (mounted with windows 7) and used command prompt and deleted all "pcmcia" realted files from C drive. Now using F8 function

I can't use any option (all option safe mode, low resolution, startup repair,etc won't work, even changes in Bios setting won't work). Also now while booting my PC with USB, after starting windows page, black screen appears with white arrow and it won't go further this black screen so now I can't even use command prompt & Installation option .

Now I don't know what to do :(
Any help will be appreciated :)

Answer:Satellite L300D: black screen during repair & boot - stuck on classpnp.sys

Did you upgrade from within Vista or did you do a clean install when you upgraded? Many vista drivers don't function properly in Win7 and need updating.

To avoid problems, you should do a clean Win7 install and use the L300D Win7 drivers on the Toshiba website.

Hi,

I have a Satellite P500-15E and when I boot it the screen is black. I then close the lid to put it in Standby mode, then open the lid and the screen is working normally.

When the screen is black just after a boot, if I connect an external display, I can see everything normally on the external display.

My drivers are up to date.

What's the problem? Thanks a lot for your help.

Cheers

I have tried to boot in safe mode, but all I keep getting is the black screen.

Answer:Satellite L505-S5993 - black screen, unable to boot in safe mode

Hi

I assume you?ve got a blinking cursor in the left upper corner.
Is this correct?

Usually this appears if something is wrong with the HDD or partition.
In your case I recommend to boot from Recovery disk in order to reinstall the OS again.
Maybe this will help you to get the notebook running again?

Dear supporters,

Model: Satellite L775D-10W
OS: Win7 64 bit
Problem: The booting procedure gest stuck after "Windows loads data" and a progress bar undertitled with "Microsoft Corporation", resulting in a black screen and a moveable mouse cursor.

The same problem occurs everytime...
pressing F8 >> all options (icluding safe mode) >> boot gets stuck
Booting from Win7 64-bit DVD >> boot gets stuck
Booting from Win7 64-bit DVD >> all options >> boot gets stuck

Is it likely that the graphic card is broken or that the corresponding driver is not fitting anymore?

Thank you for your time in advance!

Greetings

Mat

Answer:Satellite L775D-10W - Boot stucks: Black screen + mouse cursor visible

Graphic card problem might be possible but in such case the POST (power on self test) would not be passed and in my opinion it would not be possible to access the BIOS.

However, this is just a theory?
Try to boot the notebook using some Live CD like Linux

I would also recommend you to start the advanced boot menu. (pressing F8) and to choose Repair my Computer option.
Then choose ?Toshiba HDD recovery?

This option would recover the notebook back to factory settings.

I don't know how but my Grandson has seriously broken his Satellite C660-2EV

Boot from HDD - Boot Mgr not found

Boot to recovery partition - Boot Mgr not found.

Boot from a (Generic) Windows 7 install disk - boots, starts to install, finds it has not got a required driver (but doesn't tell me what it is). Allows me to access drives C:, D:, E: and X:

Boot from Toshiba recovery DVD. White bar gets around 25% across screen then stops with "You have removed USB media during install" (or something like that, laptop currently in pieces).

Removed and re-seated memory and DVD drive. Removed HDD, plugged into my PC through USB adaptor and scanned the two visible partitions (300Gb each) at bad sector level. No problems.

Help! I'm out of options.

Laptop must be (basically) functional as it will boot from (non-Toshiba) DVD.

HDD seems OK when checked externally and from (Non-Toshiba) boot

What's left?

Answer:Satellite C660-2EV doesn't boot - Boot Mgr not found

All you have done is right and I would make the same tests.

Set BIOS to default settings and test it with another HDD, if you can obtain one for testing purposes.
I cannot say for sure but somehow I feel HDD is the troublemaker.
Try to install original recovery DVD on new HDD.

I would really, really appreciate any help on this one.

On Saturday I bought a Toshiba A210-17I. On Monday, I plugged it in, to charge the battery and when it was charged, switched on - Vista completed the installation and everything seemed absolutely fine. I powered off overnight but this morning, I am getting problems :-(

When I power up, the system appears to boot and in due course, I see Windows is Loading Files, followed by the "(c) Microsoft Corporation" message with the progress bar. This scrolls across the screen for a while, the HDD light flickers a few times and then the screen goes completely blank and it is as though the laptop has gone into some sort of hibernation mode - the Power light (O with a vertical line) remains on.

Exactly the same happens if I boot from the "Product Recovery" DVD - having pressed [F12] and selected to boot from the DVD Drive.
The installed OS is Windows Vista Home Premium OEM.
The battery is fully charged.
Memtest86+ v1.70 hasn't found any errors.

Any suggestions as to what I can try next? I don't have any data on the system so I don't care if everything is refreshed, I just don't know hoe to proceed. Incidentally, I do have access to (legitimate) copies of Windows 2000, 32-bit & 64-bit XP & 64-bit Vista if that will help in any way?

Very many thanks for any useful feedback ;-)

Answer:Satellite A210-17I doesn't boot as it should - actually, it will not boot

It seems that I have now resolved this problem. I couldn't get anywhere using the Toshiba "Product Recovery" disk (which quite frankly, I might as well throw away since it doesn't appear to work) or a Vista installation disk.

In an effort to get round the problem, I tried installing XP Home. I booted from an installation disk, deleted the "Data" partition and reformatted it to install XP onto. XP reported that the laptop needed to reboot to complete the reformat (not seen that before). When it rebooted, out of curiosity, I allowed the laptop to try loading Vista - it started to do so and then announced that it needed to correct a problem. I left it for a while and when I went back to it, Vista was running again.

The only thing that I can think of was that the MBR must have gotten corrupted.

It is most unlikely to have been a Virus because the laptop had only been on the Internet for a few moments to complete the initial setup / registration - after which it went wrong.


I had thought of proceeding to load XP so that I could have a dual-boot system - however, setting up a system to dual-boot Vista & XP doesn't seem anything like as simple as dual-booting XP & Linux, so I will forget about that for the present.

My Dell computer is frozen and won't go past the splash screen. Pushing the function buttons for setup or the boot menu doesn't work so I can't change any settings or configurations.

Tecra S1 Model PT831E-107EQ-GR

Problems started a month ago. It randomly didn't booted. After some power off/on tries it finally booted and worked properly. Because it happened more often I've bought a new hard drive (Toshiba 40 GB). I've had Acronis True Image and planned to make a disk clone to the new drive. The problem is that a notebook now doesn't boot anymore so I cannot boot it from A CD nor hard drive. It stops at "In Touch..." logo with "Press [F12] for the boot device selection menu" text and doesn't react any key. I tried to boot with no CD, no hard drive - the same. I also connected internal HD using ATA-To-USB adapter - the same. Does it mean that's not a disk problem but motherboard or other components? Is it possible to enter BIOS before boot selection screen?

Regards,
Jacek

Answer:Tecra S1 doesn't boot and hangs at (boot) splash screen

Hello Jacek

Try to enter BIOS settings using ESC at start up.
The whole issue is strange and I don't believe someone here can offer exact diagnostic. The fact is you can use several bootable devices but if HDD or CD/DVD doesn?t work there is something wrong with motherboard. Maybe is HDD or CD/DVD controller defective.

I have a IdeaPad Y560. We have had a strange problem for some time that I'm not sure how to solve. The laptop works fine once you've booted into windows but for some reason pressing F2 or F12 to either enter the boot or setup menu does not work. The screen simply goes black and stays that way. It is almost like I'm in the bios but can't see it on the screen. I have update the bios via the OS without a problem but the issue remains.  

Answer:Ideapad y560 will not boot to bios(Black Screen) but will boot to windows 10 and function normally

Same here...the problem started with me trying to update to windows 10.. Initially the update didnt work and i got reverted back to windows 7.. Later, however, i downloaded the win 10 ISO manualy and was succesful in updating to a Windows 10.. Within a couple of days however, all I got was a blank screen on booting to windows(the lenovo and BIOS worked currently until that time). So, I made a live win 10 DVD and reset my installation to a fresh install (kept my files). The installation aborted mid way.. Then, I had to reinstall freshly without keeping my files..Now, Win 10 works alrite but then while trying to go to my BIOS menu, nothing happens and I just get booted straight to the Windows environment..Can someone tell me what happened?
