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 (This link will automatically start a download of Reimage that you can save to your computer.)

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.
Are you into opening the system case and dealing with internal parts?

Hi there

Pretty much every time I turn on my laptop I am being asked to enter in the date, it defaults to 1.1.2015. Does anyone know why this is happening and how I can overcome this issue? Just to be clear this happens right at the point of turning the computer, i.e. before Windows even starts to load up. It must be date/time settings of the device.

Thanks for your help in advance

My laptop cannot tell me any post after the Toshiba logo just black screen. Cannot get into the bios or anything... These are the things I have tried:
Taken hard drive out,
Taken ram out and only tried one..
Taken Battery Cmos battery out for a few minutes..
Had a look at the motherboard and fan is not even working when I turn it on..
I have taken the cpu and put it back in..
Defiantly Sounds like the motherboard problem but want to know if its just a chip that needs to be replaced and soldered.. If anyone has any ideas that will be awesome.

I've only noticed today that when I turn up my laptop's volume up to about 28 (even with headphones in), there's this high pitch noise that comes from the speakers. And I'm sure it's the speakers and not anything else.
But the sound is sort of that real ear-killing noise so I can't listen to it for long. It even sometimes sounds like thousands of crickets - a complete nightmare

But with my volume at any level below 28 I can listen to whatever through headphones without the sound bothering me.

Does anyone have any ideas for a solution? I do know a thing or two about computers but nothing about anything extremely technical and I'm not sure if I want to take it apart, unless I really have to.

If you could help me it would be appreciated!

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???.

Hi everyone, I'm very sorry if this has been asked and answered before. I have a Toshiba Satellite L305 series laptop running windows vista home premium. Last week I got a blue screen that I didn't read in time so I don't know what it said, and then it shut down. I tried to restart it but only get to a black screen with a moveable white arrow. I tried using windows startup repair, it gives me a white bar at the bottem that says loading files then the windows copyright screen but then just does the same thing and goes back to the black screen. I've tried booting in safe mode, booting with last known good configuration, and system recovery. I've also tried using a recovery disc, that I had to buy from toshiba b/c I lost my disc in a move, to no avail just the same black screen. Any help would be greatly appreciated. BTW when I put the recovery disc in you can hear the disc spinning and the fans working until it gets to the windows copyright page then everything dies down and black screen time.

Answer:Toshiba satellite screen went black ?

It sounds like a disk error or start-up error - take it back if it's still on warranty because you probably need to reformat (delete everything) and reinstall Windows.

Alright, so im not sure if this is software or hardware issue, but my satellite restarted for an update about a week ago and turned back on with a black screen. I tried taking the battery out, pressing the power button for 60 seconds, restarting it, starting in it safe mode, factory resetting it on startup. Nothing. Sometimes the fan will be running, then the machine stops. Sometimes it will just run and stay on the black screen. Sometimes it will start up and the power button wont even be lit, but the fans, and the led for caps lock will be on. Is it time for a new computer, or is there a way to fix this?

Hi there, I have a Toshiba Satellite A200 and just today I've encountered a frustrating problem. Let's just get a few things out first.

I had intended to turn it off last night, but it didn't shut down. There was some message about a program still opened or something like that (not a big deal I thought as I had gotten it a few times before). I just clicked whatever it was that ended it or turned it off anyways. So today I come back to turn it on and it was on that message. I turn it off and come back later to turn it on. I noticed there was a black screen and I could not do anything. I hold the power button to turn it off and restart it. It loads the Toshiba/Phoenix screen fine. Then I get to the Windows Recovery screen. It gives me two options.

- Use the Windows Recovery thing to try to find and repair any errors
- Start Windows normally

I tried the first option a few times but it said there was an unspecified problem due possibly to some hardware configurations (did not do anything before). I restarted and pressed F2 and looked for anything that might have caused it and I exited without saving any changes (Toshiba/Phoenix thing) and then it led me to the screen with the Safe Mode and other options. I chose Safe Mode just to see and it led me to the log-in screen, but after that it would not let me see those same options again. Anyways, I would start normally and at the loading screen, the bar would load but there is no Vista logo. After that, there's ... Read more

OK first off I'm sorry that this ends up being my first post. I work in IT as my day job but I know more about the quirks of machines I've been dealing with for years. Anyway I have a friend with a Toshiba Satellite A665-S5176x and it will look like it's booting fine and then it shows nothing but a cursor and a black background. BEFORE any of you suggest anything please look over what I've done (listing in order)

1. Tried to boot in safe-mode (same thing)
2. Tried window 7 disk (wouldn't show anything besides black no system repair)
3. Tried to boot normally and the PC BSOD'd and then rebooted...then blank screen
4. removed HDD and put it in my laptop where it booted just fine (so not a software issue)
5. Looked for mini-dump to see if BSOD info was such luck
5. since I had my HDD out anyway I put it in the toshiba to see what would happen, it black screen'd as well.
6. reset bios to default...nothing changed

At some point I saw an error mentioning a hardware failure but I don't remember when I saw it. More importantly if anyone has any other suggestions I'm willing to try them. I'm at a loss here

Answer:Toshiba Satellite always boots to a black screen

So you get the usual POST and then it just goes to the wonderful Black Hole of Death, right?

No other messages whatsoever.... but at least eliminated the inverter (backlight) as being toast since you did get POST.


Reseat the RAM and clean the contacts.

Clean the inside of the laptop out including all the fans + intakes of dust bunnies.

I'd remove the CPU heatsink and redo the thermal paste with Artic MX-4 (best available), same for the chipset's heatsink if applicable.

I would put in a trusty Linux Live CD (I use Linux Mint's) and of course set the bios to boot off the DVD drive and see if that WORKS or not. [If it can't handle that, then you know it's a shot motherboard, which is the likely scenario, since the video is integrated.]

Could check the voltage on the power supply with a multimeter, also, make sure it's not shot.

See where you are at after those things.....

Hi everyone. Im new here and was wondering on, how do i get the screen back, as I've just changed the screen ribbon on toshiba c660 as my old ribbon had broken wires. Everything works and can hear the fan etc but no screen. I noticed though that if i shine a light on the screen i can see the background. Im not computer minded but need help. Thanks

Answer:toshiba satellite c660 black screen on xp

Hi mw_86 and welcome to TSG.

Have you tried an external Monitor ? I would do that first if possible and if it's display is good carry on below.

With those symptoms if that model has an Inverter I would try switching it with a known working one.
You should find some on Ebay. (I've had good luck even with used ones).

If it does have an Inverter it could be the backlight instead but that's usually much more difficult to replace.

If it's an LED model (ie no Inverter or Backlight) I would guess either the LEDs have failed or they aren't getting power from the motherboard.

Dear all,

I have Toshiba Satellite M70, I need help and i will describe my problem:

- Few days ago my screen went black suddenly, i don't know how cause i was away from the laptop.
- Until yesterday, when i boot my laptop, it gives me black screen all the time but when i put him in standby mode by closing the notebook for few seconds and then i click the on button, my screen starts displaying fine until my next reboot and i start all over again ( i usually keep my notebook working almost 18 hours which means there's a lot of time to my next reboot)
- But Today, I booted too many times , it gives me black screen and the standby mode doesn't work anymore. But few times today when i was trying to boot, the screen displayed the Toshiba screen for only 1 second then gone black again.

P.S. You can see hardly threw the black screen everything if there is a sunlight facing the laptop.

Thank you in advance,
Best regards,
Mr. Mher Krikorian

Answer:Black Screen on boot- Toshiba Satellite M70

> You can see hardly threw the black screen everything if there is a sunlight facing the laptop
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!

sometimes when i power it on, itll give me the options of safe mode and all that. but when i choose to run normal, itll run normal for a second and then it will turn black. it has to be my internal hard drive right? if its displaying at all on my screen like options of safe mode, it stays on the whole time on safe mode. but turns black when i choose run normal

Answer:Black screen on my toshiba satellite latop

If Safe Mode continues to run without crashing or shutting down, there is nothing wrong with the hard drive. A faulty hard drive or motherboard would affect Safe Mode just the same as Normal Mode.When Safe Mode runs okay, but Normal Mode does not, it is usually caused by a bad or incompatible device driver that you've recently installed, or some incompatible software that you've recently installed of the types listed below:Third-party Firewall software.Antivirus software.CD/DVD burning software.Virtual CD software.If you can remember recently installing a driver or any of the above software types, uninstall it in Safe Mode. Then try starting Windows normally.

I bought a VGA cable to connect my laptop to my TV in order to mirror what ever is on my laptop screen. My TV did not pick up anything when I checked the Sources.

I opened the "Action Centre" on my laptop and selected "Project". I changed the current setting of "Duplicate" to "Second Screen Only", this caused my laptop screen to go black when the VGA cable was connected. When I disconnected the VGA cable my laptop screen came back on. This frustrating because I want to change it back to "Duplicate" but it is impossible to navigate while the VGA cable is plugged in because of the black screen.

note that when i changed it to "second Screen Only" my TV still did not pick up my laptop.

My Toshiba Laptop is stuck at black screen after I was disassembling it. I was opening it because I accidently resetted the bios security settings to default. Suddenly the bios password box is opening while booting and wants a password. After searching the Internet I found out that my laptop wants the supervisor password which I don't own. Couldn't call Toshiba Support because I temporarily have no phone. So I decided to open the laptop to reset the CMOS. Removed the battery and fully disassembled the laptop till the motherboard was naked. Then I found the CMOS jumpers. But there where four of them and I couldn't find any instructions for four jumpers so I decided to close the device. After fully reassembling it I turned it on and the screen was all black. Only the white LED was on and the light round the power button. Tried many instructions from the Internet again but nothing works. Not even the USB ports seem okey cause when I insert a stick in all of them the lights for 'stick is working' are out (my USB sticks got LED's) Then I linked my laptop via HDMI to a friends TV. No signal. I'm crushed. Help me pls!!!!!!!!

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


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 [] 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

Power indicator and adapter indicator below keyboard light up faintly white. Battery indicator goes orange momentarily if I put the battery back in.

Answer:Satellite A200 - After Toshiba screen the display does black


Normally after the Toshiba screen the notebook tries to boot from HDD.

It could be a HDD issue but I?m not sure. Have you checked the BIOS if the HDD is recognized properly?
What happens if you load the default settings in BIOS?
Did you test and external monitor?

Last but not least it would be interesting to know if you can boot from another device, for example CD/DVD drive.

Answer:Toshiba Satellite Radius Laptop black screen

Try an external monitor on it as first step.If you never ever see anything at all on the screen then it is almost certainly a hardware fault but what happens on the external will tell us more.Also let us know whether the computer "appears to start" or not (lights, fan sounds etc).Always pop back and let us know the outcome - thanks

Hi there,
Today my laptop (windows 8.1) ran out of battery. Later when it was charged again, only a black screen with a cursor appears. Additional the power button does not work. When I press the power button the laptop does not shut down nor boot again, just the black screen with the cursor appears again. Alt+Ctrl+Del does not work either... I don't know what I can do else. Can anybody solve this problem?
Thank you very much for your help

Answer:toshiba satellite u920t black screen with cursor

Press and hold the power button - does it turn off and on again ?
if so do three times in quick succession - this should trigger the repair your computer screen - select start up repair - see if this solves the problem.
If you can't get to that point do you have a windows DVD?

Toshiba Satellite L655D-S5109

A month ago was having issues with infinite start up loop after bad updates install. Couldn't even get into the command prompt for a while but then was able to and followed the "How to Recover from an Infinite Looping Startup Repair Loop without Reinstalling Windows" guide that I found on here and it worked. Got all of my personal files off then after a couple weeks decided to do a factory reset because it was starting to run slow at times.

Two nights ago had more updates from Windows and when I turned it on it said something didn't download correctly. It did a disk check and then was fine except ran slow when it booted up for a few minutes. Today when turning it on it gives options of running StartUp Repair which does the Windows loading files screen then goes to a black screen with the cursor icon. Also gives the Start Windows Normally option which gets stuck on the opening Windows icon and never moves.

All F8 options end up with black screen with cursor and the kicker is that I attempted factory reset twice now and it goes to a black screen with cursor as well. I don't have a recovery disk or any other Windows media.

Is there anything else I can try (tried taking the battery out too and holding down power button) or is this laptop toast? Thanks and let me know if you need any other system specs.

Answer:Toshiba Satellite - black screen of death and can't even factory reset

I would say that you have a disk problem.
If you do have a Win (7, 8 or 10) installation disk, boot with it, go to repair, launch command prompt and then type chkdsk C: /f.

Hi. I'm basic computer user posting on behalf of my grandad who lives several hours away. I've been trying to help him by phone but no success so far.

He has Toshiba Satellite L350D running Windows 7. For several days he's met black screen on startup. He's tried a few online suggestions (that I found via Google) that didn't help (hold power 30 secs, hold power 60 secs, remove battery, external monitor, several function keys). A couple of times he found tapping f11 during startup enabled him to use laptop, but that way has since failed to work.

Any other suggestions would be much appreciated.

in the beginning of December I bought the above notebook as second hand.

The fomer owner told me that after a Windows 10 update (original OS was Win 8) the Notebook shut down and for him it was not possible to get access neither to the operating system nor to the BIOS. He said he had tried it with all known key combinations.

I have to note, that the notebook came with a non-original HDD (a 320 GB Toshiba HDD) and a non-original power supply (Fujitsu AC Adapter with 4.22A/19V).

Back at home I tried myself several ways to get access to the BIOS (pressing F2, FN+F2, F8, F12 and futher more), but I have not been successful.
Connecting the notebook with a external display gave no signal.

I already thought that I got a complete defektive notebook, although the LED on the frontside were glowing, the battery was obviously charging and the cooling fan startet. The DVD drive also blinked after pressing the power button. Funnily enough the "Num Lock" light was glowing green and I was not able to eliminate it.

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.

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 everyone,

I am having an issue with my Toshiba notebook. My model is Satellite A210 - MS508C. I am out of warranty.

Originally, I was having problems turning on my computer. I would push the power button to turn on the computer. Usually, there is a Toshiba loading screen with a bar at the bottom showing the loading process. Right after, there is a Windows loading screen with another bar at the bottom showing the loading process. I was having problems at the Toshiba loading screen. It would load about 75% and then freeze. My computer would not turn on and I would have to manually press the power button to turn the computer off. Then, press the power button again after waiting a few minutes to try to turn the computer on again.

After having this problem for a week, I figured it was maybe because my computer is not as updated as it should be. So I went to the official Toshiba website to their updates page. I started to download the BIOS update.

In the middle of the installation, my computer shut down (turned off) by itself. There was no indication that the installation was complete. I also remembered reading that the BIOS update should restart automatically. My computer turned off itself all of a sudden and did not turn back on. After waiting a couple of minutes, I tried turning it on manually by pushing the power button. There was sound and the blue power button light below the touchpad was on. However, the screen was black and blank.

I have two C70D's. Both died within weeks of each other, and went back for repair with RepairTech, under warranty.

Both machines failed to boot, with an error code(?) of three flashes of the power button.

One machine came back within a week, fully working.

The other took three weeks, came back with a change of motherboard (they say). I unpacked it, and it was still not booting, still flashing three times on the power button.

I phoned repairtech, immediately, sent it back, the next day.

Today it came home, again, I opened wont boot, and does the same three flashes on the power light.

Back on the phone. They've booked it in again, saying maybe it's a peripheral. The only peripheral is the power adaptor. I have two. It doesn't work with either.

I believe the problem is battery related, but it's an internal battery so I can't open it without voiding the warranty.

Has anyone else had problems with RepairTech? Does anyone know if this is a battery problem?

I am at the end of my wits end....
This started on Sunday. I noticed that when I switched it on it behaved as if it had gone to hibernate when I know I had switched it off. It then went black and remained black.
I have tried all the usual battery tricks and eventually, it agreed to start POST-ing again.
Monday: It starts up ok but not internet connection whatsoever. Eventually, after updating the atheros card my interconnect connection worked again. It could have been coincidental, I don't know.
Tuesday am: I switched on briefly to check something and everything seemed fine. Away the rest of the day, computer switched off.
Wednesday am: switched it on and it went to black screen again. This time all the usual battery tricks did not work. I have had a variety of black, white and grey screen throughout the day. At one point, I had a striped screen...
Today I am trying to find someone local who could lend me a computer screen to check the state of my screen.

Anyone got any idea and constructive thoughts that will take me out of my despair?!!

When you say it does not boot into a BIOS, are you tapping F2 while it's booting?

If that does not work, holding ESC for 3 seconds usually works, IIRC.

Hey there everyone, hope you are having a great day! So my P71 was delivered on June 12 and today it was sitting on my desk, where it had been for DAYS, I wiggled the mouse to resume it from sleep. The computer flashed into windows for a VERY brief instant and then completely died and the screen went black.  I immediately unplugged the laptop from the charger and tried to turn it on, the keyboard and power buttons light up like everything is working perfectly  but the screen remains totally black and then a very loud series of about 5 beeps comes out of the laptop. These beeps are arranged almost like a song. Then nothing happens and the computer remains black. I have to hold the power button to get it to turn off from this state. Called support and they went through some "battery in, battery out, charger in and shake it all about " but to no avail. Didn't opt for any kind of extended warranty on this laptop. I've been treating it like a new born child; it is 3 times more expensive than any other laptop I have ever owned... I can't believe that I finally decided to purchase a professional grade product and this has happened after only 5 weeks of ownership AND such "babying" of the product. Phone support told me that the beep code I am hearing is something to do with the motherboard or memory, but I didn't touch anything from my original config and have caused NO CONCIEVABLE damage or stress to this machine in any way.

Thanks for writing to us. 
When did the issue start? Have you made any hardware or software changes. 
Does it beeps in a sequence. If possible please send us an audio file of the beeps sequence,as per that we can make out what is causing the trouble. 
Meanwhile you can try the following steps
Disconnect the power sources , hold down the power button for 15 sec, then put back the power sources, power up the machine and observe if any changes. 
Also if possible remove the memory modules and put them back one by one and observe for changes. 
Please go through this link for instructions on memory module removal

Hi to everybody,
I have experiencing strange problem, when turning on the laptop.
It doesn’t boot, just Toshiba logo appears on the screen.

Once it took to the point where it shows “Starting Windows…” and the scale below.
Then it stayed for a while like frozen and turned off.

I can shut it off by using power/restart button as well.

My strong guess is that hard drive is dying.

What do you think guys?

Answer:Toshiba Satellite 2180CDT – no POST, just LOGO.

Do you have a bootdisk?
I think that notebook has windows 98 correct?
If you have no bootdisk please go to and get one for your OS.

Once you have the bootdisk start the computer with the disk in the drive. If it will not boot from the floppy you must enter the BIOS (usually by tapping the DEL or F2 key upon startup) and set the boot priority to floppy/cdrom/hard drives.

Once the computer has loaded with the bootdisk you will come to a DOS prompt. At the prompt type the following (no quotes): "scandisk c: /all"

You may be lucky and get away with a bad boot sector. Post back with results after scan.

Hi, I have this 4 year old Lenovo Y560(config below)

The discrete graphic card has probably fried a long time ago, so last year when I did a clean install of Windows, I had to disable ATI Card permanently in the device manager using safe mode and used the Intel integrated card. A few days ago, I booted up windows only to encounter, "A disk read error has occurred, press ctrl+alt+del to restart" . I tried to boot up using WIN 7 install disc, but soon after the Starting Windows logo , the screen turns black and I am left with a cursor in a black screen. I tried to boot into Safe Mode but still I encountered a black screen with just the cursor .

I booted with Ubuntu live usb and was able to access all my partition and did back up and even formatted the Windows Partition. I tried to boot using a WinPe and faced the Black screen with a cursor again. I even reset BIOS to default, changed Graphics Adapter from "Discrete' to "Switchable' and vice-versa, but no effect at all. When I boot up using Ubuntu and ran lspci | grep VGA I can see both cards listed. I even tried to boot up using Windows 10 preview disk, still I get a black screen after the Windows loading screen.

I can't afford to buy any laptop presently since I am currently at college, so using Ubuntu for now. Is ther any way to install Windows 7 again? Is it possible to get the ATI Card working properly- reballing, reflow?
Any way to permanently disable the ATI card and get w... Read more

Answer:Black Screen During WIN 7 POST , Black Screen Even In Safe Mode

What other graphics adapter choices are available in BIOS setup? If you choose Switchable is there software on the Lenovo site for your model that's needed? Are you using the Display adapter software from there?

Have you tested your HD with the maker's HD Diagnostic extended CD scan, followed by a full Disk Check on a single disk partition you create?

Then work through the steps for Overcoming Windows 7 Installation Failures - Windows 7 Help Forums including trying an alternate install method (disk><flash stick) with new media. These steps overcome almost all install failures, so you'll be reasonably sure the problem is hardware or BIOS settings if nothing works. But don't skip any steps.

Try Clean Install Windows 10 Technical Preview to see if there's any difference with a more modern OS install. It's already a very polished OS and worth testing this.

So on my computer, something strange happens when I uninstall UxStyle. It has broken my Windows install once and it has done it again. The first time, I kept on doing system restores to see what was the problem that made that black screen. After trial and error, I narrowed it down to UxStyle. So, I deleted Windows 8 and installed Windows 7, which is what I wanted in the first place. Now, I decided to triple-boot Windows 7 with Vista and 8.1, and it has succeeded. I reinstalled UxStyle thinking it was just a problem with my old Windows install, and then uninstalled it after a few days since I felt like the regular look was better. I rebooted Windows and the same effect happened.

So, I would like to know if I can get and replace those three patched DLLs with unpatched DLLs for Windows 8.1. Could I just change the broken ones to have .old next to them and then place the ones I get here there? Also, would sfc /scannow work?

Answer:UxStyle Black Flashing Post-Windows Update Black Screen

Hello lct01a, and welcome to Eight Forums.

A sfc /scannow will attempt to repair any modified or corrupted system files, so that would be a good first step.

at first when turned it on it was a black screen saying the computer was not shut down properly. my dad told me he just clicked start normally. then when it came back on it had this problem. when turning on the computer the monitor says no signal and then goes black. there are 2 beeps. the 1st seems like a short/medium beep and the 2nd one is a longer beep.
the computer is an HP.
what does this mean?
sometimes they use this computer for internet, but mostly my dad uses it for games. just simple games like casino.

Answer:computer problem. black screen no signal, beeping

I wanted to answer myself.
it looks like everything is good this morning.
I opened up the side of the computer to see if I could identify the RAM. the RAM are the 2 pieces that fit into slots? I undid the one pulled it out and put it back in and clipped it back in. don't know if that did anything.
I turned on the computer this morning and it gave me 2 options. either start normally or start with repair (recommended). so I started it with repair. it said it was attempting to repair and may restore the computer to an earlier version. after doing all that it looks like it repaired itself, because I was then able to start the computer again and everything looks the same as it was before.
I would still like to get some thoughts as to what could have happened? and is this something that seems to be totally fixed? or should I be watching for things to happen again?

Dell-Sahana R,
Thanks for your reply, I think there is a problem in BIOS, I download latest BIOS updates from DELL support and then Install it and problem is fixed, I think there is a problem in BIOS software it might be CRC error or any checksum error something like that,
But I fixed this problem updating BIOS,
Again thanks for your reply.

My Dell Vostro 3560 rebooted after installing the latest updates for Windows but when it restarted it showed flashing buttons on the keyboard and then only a black screen with a slow continuous beep.
The beep sounds once every three seconds and just keeps repeating continuously.
After googling for a while, I found the advice to remove the battery, unplug the laptop, hold the power button down for 60sec then plug in the power again and try to reboot. 
This initially worked. But I decided to try and figure out what had caused the problem by rebooting again with the battery removed. 
The same error occurred but this time I couldn't get it to boot by doing the process described above. Every time I tried to reboot it showed the flashing three buttons on the keyboard, then a black screen with a continuous beep. I do hear the fan startup and it sounds like the harddrive starts working. 
Some more googling, and I learned you could start ePSA diagnostics by holding down the function key while pressing the power button to start the laptop.
So I did this and the screen started up and showed the Dell loading screen. It then ran the ePSA diagnostics but that showed that everything was ok. After ePSA the only option is to reboot so I did that and again the same problem: black screen with beeping. So I rebooted again holding down the function key and when the Dell screen was shown and I was able to press F12 and go into the boot options. After looking at the bio... Read more

And sorry lads for my english


Answer:hp pavilion dv6152eu black screen and beeping..Need advice

Get the beep codes from HP tech support... they tell you what is wrong. It is either the Video Card or memory.. or perhaps just dirt and hair around the cpu... as crud stacks up fast in that model.
If you have been using that computer as a gamer, it is definitely the video graphics card.

Hi There,
I have a friends Toshiba Satellite A200 that when starting does not get past the post, you get the screen "In Touch with Tomorrow Toshiba" Press F2 System Utilities, or F12 for boot menu. The blue bar get about 3/4 of the way accross then it reboots. Even if you press F2 or F12 you get the same outcome.

Any help would be appreciated.


Answer:Satellite A200 - Post cycle boots on - In Touch with Tomorrow Toshiba


it looks like a Bios corrupted and need to reflashed. The problem is that you need dos-based bios and floppy disk to reflash it. On the Toshiba driver page, there is only Win -based one.
Note, I just suppose that is Bios trouble maker but it can be mobo related issue itself.

Anyway, you should contact the service center, it's not impossible to solve such issues in this virtual forum

I tried turning my laptop on and the screen is just blank, the battery is fine all the LEDs come on but it doesnt start up. It beeps every 2-4 minutes.

Can some help or advise please

Answer:Satellite U400 - Screen is blank and gives a beeping noise


Generally speaking such beeping codes mean that a hardware malfunction was detected so have you changed something on hardware configuration?

If you have installed two RAM modules you should test it with single module only. Sometimes it happen that RAM modules are defective so try it with one module only. Maybe it helps :)

My wive purchase this computer coupple of months ago. It was from the beginning ferry slow on windows 8
The wurst laptop we ever had. We feel robbed of our money.

2 months ago we started with Ubuntu. It Still slow. IS there anybody with the same problems?



Answer:Satellite C70D-A-108 is very slow

Hi Marco

I don't have this notebook model and cannot confirm what you wrote but fact is that almost all new notebooks are pretty slow at the beginning. Many applications are set to start with Windows and this, of course, slows down boot time.
Windows updates are also set to automatic so in the background the machine will download and install many updates so this will slow down your machine rapidly.

In my opinion you should install original OS that you got with this machine and optimize it a bit.
Remove all useless stuff, change start-up option and disable automatic Windows updates.
In the past I have noticed that original preinstalled antivirus is also responsible for notebook?s performance so I don't use original preinstalled application but my own version of Avir Antivir and it runs perfectly.

Check all these options and I hope your machine will run much better than before.

Just bought a Satellite C70D with Win 8.1. Everything works (as far as I know until know), except boot from DVD. I disabled in the bios the Secure Boot and changed the boot order to DVD first, then USB and then HDD. The DVD drive starts, but then it skips to the HDD and Windows is started. First time I tried there was a message like "DVD boot not supported" or something like that.
The DVD is bootable, so that is not the problem.
I would like to install Linux Mint alongside Windows.
Anyone solved this problem already?

I'm looking for a new display for my Toshiba Satellite C70D-A-11K!

Please help!

Answer:Need new display for my Satellite C70D-A


The Satellite C70D-A-11K was equipped with the 17.3" LED color LCD panel with the supporting max resolution of 1600 x 900 px
You should be able to order such display panel from local Toshiba authorized service provider or you could check some 3rd part online dealers who provide compatible notebook parts…

As I mention above: you should look for the 17.3" panels.

I have a C70D-A-107 and want to speed up this notebook. Already placed 4gb extra memory so the notebook has now 8gb internal. I doubt whether it is usefull to put in 2x8gb. I think the processor is just to slow. It has a AMD E1-2100 inside. Is it possible to put in another (faster) processor?

Answer:Speed-up Satellite C70D-A-107

The Satellite C70D-A-107 was equipped with an AMD Essentials E1-2100 Accelerated CPU (1,00 GHz, 1 MB L2 Cache)
It’s not the fastest CPU therefore the notebook performance isn’t the best…

But CPU upgrade isn’t officially supported by notebook manufacturer... therefore I don’t think that you will be able to upgrade the CPU…

I read about successful Intel CPU upgrades but did not meet anyone who was able to perform an upgrade with an AMD CPU

Hello everybody,
the Toshiba Sat C70D-B-317 (PSCLEE01L009FR) is on it's way and I don't have it for the moment but I would like to know if there is a way to add some Ram to this machine without opening everything?
Also, is it possible to change the HD in the future in the same conditions?

sorry, but it's my first PC laptop and as a Mac user I'm completely lost with all these models and different serial numbers.

I thank you in advance for your answer.


Answer:Satellite C70D-B-317 - Ram upgrade

1. yes you can upgrade your RAM, This laptop has 2 slots with one 4GB standard so if you would you can put one more 4GB. With 2x4 you have Dual-channel and that works much faster than single

I don't know if your HDD can e upgraded. When it's not possible you can always buy a external HDD

Good evening,

I'm sorry to disturb,
but I find myself in a situation to which I find no solution,
that's why I come here asking for some help.

A friend has just purchased the following laptop:
- Satellite C70D-B-307

but the worry is that apparently it is impossible to have access to the HDD recovery to execute the factory restoration.
I try all possible solutions that I find on the web and none of it works.

what to do ?

does Toshiba sell the recovery DVDs that will restore the computer to its factory state?

Thank you very much .

I've been working on a dell inspiron 1525 today and cant figure what is causing this problem.

The laptop boots, displays the post screen, and then the screen goes black.
You can boot into BIOS,
You can boot into the Boot menu.

You cannot boot into safe mode, the f8 key does nothing,
when using the boot menu, u can't boot into a windows disc to reload the operating system, it just goes black.
I did however manage to boot into a linux cd i have and run a HDD test (what passed) and a memory test (what also passed).

It does exactly the same on an external monitor aswell so I am lost with this one.

Any ideas would be appreciated

Hi There,

I have had a Satellite C70D for about 18 months now, but have not used it in the past year as I have been disputing with customer services about the windows licence for the machine as I lost it when I formatted the original hard drive before installing an SSD and they wouldnt send me a copy of it. I have now bitten the bullet and bought a windows 10 licence again. However since building the machine a few days ago, I have been having a couple of issues and as it is now out of warranty, I cannot contact customer support (Who I found unhelpful even when it was in warranty!)

The first issue is when I boot up the machine, occasionally the keyboard will not work, I cannot type the BitLocker pin and I have to remove the battery and press and hold the power button for 10 seconds, this then fixes the issue for a few reboots before it goes again.

The second is that occasionally it will boot up with a red x next to the WiFi symbol, but it detects the WiFi card, usually a reboot fixes this but not always. I have reseated the card and still no avail.

Can anyone shed any light on what may be causing this? The BIOS is up-to-date as are all of the drivers.

Thanks in advance for your help

Answer:Can I replace the HDD in my Satellite C70D-B -00P model with an SSD?

Generally speaking yes, you can do this but problem is that your notebook model doesn't have HDD cover at the bottom side.
To have full access to the HDD the bottom cover must be removed completely but it should be done by authorized service only.

Of course you can try to do it alone but I?m afraid you may lose the warranty.
If possible contact nearest Toshiba service provider in your country, explain the situation and ask for help.

My girlfriend bought me a new Toshiba laptop C70D-B-10U (my second Toshiba), it is a good laptop apart from the speakers they are terrible. I didn't want my first post to be a complaint but, Toshiba cut corners when it put the speakers in this series of laptops.

Or have I not set them right has anyone else had this problem, any ideas or solutions thank you.

Answer:Bad Speakers on Satellite C70D-B-10UM

I think your notebook has only small stereo speakers and the sound is not the best. I have Satellite S50-B with Harman/kardon speakers and sound is really good.

You can try to change sound options but if you want to have better sound I’m afraid you need external speakers, Maybe BT speakers.
