Question: Satellite Pro U400 - BIOS update went wrong

Hello everyone!

I update the BIOS on my laptop and something went wrong, not now turn a laptop screen.

I went to see the web for Chris Bios recover.
Have available more than 20 versions, but so far no success.

My biggest problem is - I can not save to floppy disk 2 MB BIOS. All attempts to make a boot
flash or SD ended in failure.

The laptop is: Satellite pro U400 PSU45E

Please help me ... the laptop reads the floppy in BIOS with little experience (those that come with Chris Bios 500 KB - 1000 KB) begins with a normal boot beep signals supposedly provided a definition blocks then baar both short beep and do nothing ..
there must be something ... DOS BIOS small size, USB emulator .. BIOS to be torn down so it is possible charging of USB, SD ...

Every idea can be useful!

Thank you very much

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.)

Answer: Satellite Pro U400 - BIOS update went wrong

Hi mate

Unfortunately? if something went wrong during the BIOS update, then you will not be able to solve this without an help from an ASP technician?

Hopefully the BIOS ROM module is not damage?
In worst case the mobo is damage but maybe it?s not damaged?

However?. You have to get in contact with an local ASP and should ask for further handling!

Good luck!

My last BIOS update has failed and now my laptop Satellite PrU400 PSU45E is out of order.
I want to use the Crisis Recovery Disk with an USB floppy drive but I don't know the key combination to run the boot-block.
Is anybody can help me?

Best regards

Answer:Satellite Pro U400 BIOS update failed - What is BIOS Boot-block access


I wondering what Crisis Recovery Disk do you have ?:|
In my experience the special disk is needed which is available only for ASP technician.
Therefore it?s necessary to contact the ASP in your country in order to reflash the BIOS.

In my opinion you shouldn?t not try any ?Crisis Recovery disks? which you fond in the net? this can lead to mobo damage?

Is there any utility, and if so where can I find it, to update the BIOS *from DOS* and *NOT* from Windows?

The utility +should be+ *PHLASH (or PHLASH16)* but every version I download from Internet (various websites) doesn't recognise my BIOS and doesn't perform the update... is there anything official?

I ask for that kind of utility because +I don't have Windows on my notebook+ and Ubuntu Linux is not supported by Toshiba (a very strange thing).

+Thank you in advance!+

Answer:Satellite U400-15H BIOS update (DOS)

Hi mate

Unfortunately, all BIOS updates designed for newer Toshiba notebooks series are WIN-based BIOS updates and you can update the BIOS only from running Windows system.

If you have not installed Windows OS then you will have to do this in order to be able to perform an BIOS update.

I have a Toshiba Satellite Pro U400 (PSU41E) running Windows 7 x64 and I have been trying to update the BIOS to version 4.70 for 4.00.

Every time I try to do so from Windows using WinPhlash that is bundled with the download from the Toshiba site it seems to freeze when trying to flash the new BIOS.
I have logged in as the local administrator, tried using other flash programs and even tried doing so from a USB flash disk with no luck.

Can someone please help me and explain how I can update the BIOS?

Answer:How to update BIOS on Satellite Pro U400?

Sounds like you need the Toshiba Value Added Package installed (specifically for U400 and Win7 64bit), or your Antivirus Software is blocking the update.

Hi everyone,

I have a SATELLITE U400-10O (PSU40E-00R00EG3). It's an older product, but once which I still love an use regularly.

Recently, I have purchased a battery upgrade for this device. Unfortunately, the Laptop won't recognize it. The battery works, but I don't get any information on the charging level. I have tried various 'resetting' tricks (deleting Microsoft ACPI from the installed drivers list, running down the battery completely etc.).

I believe the BIOS could be outdated and I would like to update it. Unfortunately, the Toshiba Support website does not list any updates for it anymore. Does anyone still have access to the BIOS updates for this?

The BIOS is a Phoenix currently at version 4.70.

Answer:BIOS Update for Satellite U400-10O Required


N my opinion BIOS has nothing to do with it. Battery can be replaced and if you use compatible batteries they should be recognized properly. Here is the list of all compatible batteries:

Have you bought one of them and original Toshiba product (Toshiba label) or some no-name product?

Good morning,

I have a Satellite U400-112 with Windows 7-64bit OS. I cannot upgrade my system from v4.00 to v4.70 either from windows or from DOS.

Specifically, when the upgrade process starts, and after the file check it stucks without any progress. This error stands for both versions (DOS & Windows).
I have a strong feeling that is a corrupted bios file. If someone can justify my feeling or has a correct BIOS file he/she is welcome to respond.

Thank you in advance,


Answer:Re: Satellite U400-112 - BIOS update error

Hi buddy,

BIOS update from DOS is not possible because the updates are only Windows based.
Anyway, what BIOS update error you get exactly?

If you try to update, make sure that Value Added Package is installed. That?s necessary for BIOS update program.

But why do you want to update it? Normally it?s not necessary if your system runs ok.

Answer:Satellite U400-12P Problem Update BIOS


I?ve got the same notebook model and updated the BIOS last week to version 4.70-Win and everything went smoothly.

I?ve got also Win 7 OS but 32bit.

Just one question: did you unzip the package correctly before running the exe file?
You should do this in a created folder. Furthermore in most cases the VAP (value added package) should be installed on your machine.

Check this!

When I first got my computer I ignored the BIOS information, and then tried to download them.
Now I have BIOS icons on the computer but i don't think they have been installed.

When I check the information it says the last BIOS update was 12-07-08, which was about when I bought the computer, so it seems I have not updated any BIOS.

When I am notified now about BIOS and I attempt to download the correct one, a notice comes up saying 'Unfortunately your personalised list of drivers has expired'.

What does this mean?
I am not very knowledgeable about the workings of computers.
I just want my computer to work at optimum peformance; i need to know whether I can remove BIOS files (that seem not to have actually been installed), and how to get all the updates i need and only the ones I need.

Basically I feel I need to 'start again.'

I have windows Vista and Satellite U400.

Answer:Re: Why am I unable to update BIOS on Satellite U400?

First of all just one question;
Is your notebook running trouble free?

Yes? Then you don?t need any BIOS updates!

Now a general information about BIOS updates:
Don?t look on the BIOS release date but take a look on the BIOS version available for your notebook model.
Then compare it with the BIOS installed on your notebook.
The version can be checked in the BIOS inside.

Then you would know if your installed BIOS is older or not.

i thought i upgraded the BIOS but when i downloaded file from tohsiba and installed maybe i did installed it wrong i should change in the settings or something because BIOS version is good it shows the latest version: TOSHIBA V4.80
But on the SMBIOS -version it shows the oldest one ver 2.5 so please anyone can tell me or show me how to upgrade that to?

here is a pic to show you guys what i mean:


and because in this bios version there are so manny settings if i click on: Advanced Settings: FLAGS, DMI , and DEVICES but on DMI and i see "Category" and there are Motherboard , System , Chassis , OEM settings, and Other, maybe i should click so it will change to new version even in SMBIOS and not only the BIOS or ?


Answer:Satellite U400 - BIOS update question


What version is show in BIOS settings?
Go to BIOS and check this!

Usually there should see the 4.8 version?
If you will see the v4.8 in BIOS settings then your BIOS update has been updated properly.

I don't get to see the BIOS update screen else where other that the time that I did the BIOS update.

Answer:How do I roll back the BIOS update on Satellite U400-157?


To be honest I don?t understand exactly what is your problem.
You said: ?. I now notice that the screen blanks out a few times at PC start up.?
What does this mean exactly? Is your display black until Windows has booted up?

To be honest, I don?t think that BIOS update would be the reason for that? go to BIOS (press F2) and set the BIOS to default settings (F9) and save the changes (F10).

If you want to get back the earlier BIOS version, then you will need to flash the BIOS ROM module using an DOS based BIOS version. On the Toshiba European driver page you can find only the win-based versions?

Since updating the BIOS on my U400-15E (Vista 32), the illumination of multi-media keys, touchpad always turn on after reboot, resuming from sleep or hibernation. Touching the illumination off key once does nothing but the second touch turns them off till next restart.

Illumination is disabled in bios setup and also via HWsetup. After reboot/wakeup, without touching the illumination on/of button, accessing the illumination tab in HWSetup, illumination is shown as off even though it is on. Touching the on/off button then toggles illumination to on without changing actual illumination on keyboard. Next touch toggles both to off.

This is not a major pain but very frustrating. Any ideas?

Answer:Satellite U400 - After BIOS update the illumination turn on


Did you reinstall the right BIOS for your notebook? The Satellite U400-15E belongs to the PSU44E series and did you choose this model on the Toshiba website before you have downloaded the update?

Furthermore for Satellite U400 are different BIOS version available - One for 64bit OS and one for 32bit OS. So what version did you install on your notebook?

Last but not least I recommend reinstalling the Value Added Package. This controls also the illumination function.

Answer:Satellite U400 - After BIOS update I can't start Windows


Did you really choose the right BIOS for your notebook? Because on the Toshiba website are different U400 models so did you choose the BIOS for PSU44E on the Toshiba page?

After the BIOS you should load the default settings in BIOS.
Did you check this?

A BIOS downgrade is not possible. This can only be done from an authorized service provider. So you should contact them and ask a technician for help. I?m sure that they will help you. ;)

I have been recommended to do a BIOS update on the above machine. I think the existing version is 1.30 and the correct replacement is 1.70 (I think this refers to PSA33E: []).

The original BIOS has a password. Would like to know what happens if this process goes wrong. Will my system be inoperable or is there a backup procedure pre-install?

The additional problem with this is that the fan is going on every minute or so. The heatsink looks clean, but maybe new thermal grease should be applied to the cpu.


Answer:Satellite A30-931 - What happens if BIOS update goes wrong?


In worst case if the update goes wrong your computer doesn?t boot anymore. That means you can only see a black screen and you can nothing. In this case you would need professional help from an authorized service provider, they can reflash the ROM module or exchange it.

But here some important points before you start the update:
-Make sure that you are logged in as administrator
-Disable your AntiVirus and Firewall
-Disconnect from Internet
-Close all running programs

> The additional problem with this is that the fan is going on every minute or so. The heatsink looks clean, but maybe new thermal grease should be applied to the cpu.
Yes, maybe the thermal grease must be renewed if you have already cleaned your notebook. After this everything should work normally.

Unfortunately you didn't write which Satellite L40 you have exactly. I have checked Toshiba support page and there are listed three different models (PSL4xxx).
So you must be sure you have chosen the right model.
Please inform us about this.

I want also to discuss something else too. If the system runs well and stabile you do not need BIOS update. Fast or slow boot, in my opinion, has nothing to do with BIOS but with OS configuration. You must optimize start up procedure and be sure notebook must not start all useless applications and processes. It is nothing but wasting the time.

To be honest you can be happy that your notebook works because many people have had bad luck after not successful BIOS update.

In my opinion you should not ?play? with BIOS updates. At the end you will damage BIOS update and your notebook will not start at all. Maybe you should contact Toshiba service provider and clarify this. Ask for help. They should do it for you. If something goes wrong it will not be your fault.

Be careful with this. It is just my opinion and advice for you. Don?t change well running system.

Yes, the upgrade flash went wrong with me also, as so many i've seen. Weird that toshiba recommends a bios flash when you get errors installing win7/ vista, and have it fail so much.

I tried getting 3 different bios versions from the internet, 2 from the toshiba site (2.0 and 2.1 i thought) and alaa200a.rom.

When i make the crisis disk with the crisdisk.bat (even doing it in DOS) it copies all files on the floppy, also tried the different phflash versions. Older ones seem to actually load for 2 minutes, the newer ones tend to load for a few seconds then stops and starts loading again etc.

Needless to say, all my efforts with those bios haven't paid off for one bit.

When i put the notebook normally on, and when i press the Fn button on the keyboard, the Fn light actually lights up, but nothing else happens.

Anyone who might have any idea what to do more, apart from buying a new bios chip?

I have Satellite P10-874, my model number got erased from the bottom after years of use.
I recently did a Bios update from Toshiba website and later realised it was for SP10E models.

Well my system didn't crash. Does the model number (part no) change if you update with a Bios version not meant for your system?

My system is still under warranty but the new model number/serial number combo is shown as invalid global entitlement database. My USB ports are not working any more after it showed a power surge message.

I need goto the service center. Is there any way to retrive my originial model no and part no?

Any help will be highly appreciated.


Answer:Satellite P10-874: Does wrong BIOS update change the serial number?

A "wrong" Biosupdate neither erases nor replaces the modelnumber of your machine. So you don?t have to worry about when you give the machine to a sevice center, they have the possibility to retrieve your serialnumber with their system and figure out the modelnumber of your machine.

Regarding your USB-ports: send the machine to your local service-center and don?t worry about the modelnumber-stuff. Your machine is still in warranty and since they will approximately change your system pcb, your worries about the wrong bios is needless.

By the way, i cannot imagine that you have earnest a wrong bios flashed, since the machine during the biosupdate ususally shouts if you try to flash a wrong bios on it.

I assume this is your notebook and these are all the drivers and BIOS available for this notebook model:

The latest BIOS is v6.50 and it looks to be the right one.
The Pro C850 seems to belongs to the same series so possibly the BIOS is the same.

However, the BIOS update is always an sensitive procedure and from my point of view it?s not really necessary if you don?t have an serious problems.

I have a Satellite U400 Satellite.

Can anyone direct me to a support link to setting passwords in BIOS?

There are several options and I'm not sure what does what...
thanks for your help...

Another point:

I have a feeling that setting a password or two in the BIOS will help the face recognition program to work, for some reason.
I was NEVER successful in properly configuring that, though I tried several times,
going according to instructions.

Quite frustrating and time-consuming, I'd say.
So much for added security.

Answer:Satellite U400: How to set password in BIOS & How to use face recognition

> Can anyone direct me to a support link to setting passwords in BIOS?
If you want to set the password in BIOS then you have to access the BIOS pressing the F2 button immediately after the notebook has been powered up.

There is a 3rd tab called ?Security?.
There you can set the BIOS password. You would need to set it firstly and then you would need to confirm the password putting it once again?

>I have a feeling that setting a password or two in the BIOS will help the face recognition program to work, for some reason.
That?s nonsense? the BIOS password has nothing to do with the face reorganization.

Here is a very useful thread which provides all details regarding the face reorganization:

Check it. It's very useful

I've failed with bios update which I had taken the bios file from toshiba's official support page. I'm sure that I had chosen the right bios file. But something is wrong and my laptop is bricked, now.

I'm trying to recover the bios with Phoenix Crisis Recovery. I've tried 2-3 variety of the Crisis Recovery.

I have old, stable bios backup, so I'm trying to recover with this old bios file. I've tried Win+B, FN+B, Win+F, FN+F, Fn+Esc, U key combination for crisis recovery.
By the way, I'm using 1GB FAT formated usb drive for this purpose. The machine beeps every time, and I'm waiting for 10 mins or more after the beeps.

I've put the bios file to usb disk with a lot of names "bios.wph", ".fd", "bios.fd". Also I've tried to use usb floppy, but the bios file is 2MB, so I couldn't do that.

I've also tried insyde recovery solution. I don't know the right file name for the recovery.
I've looked the bios file with a hex editor, but I haven't find the file name (for example bios.fd or something)

Please *don't* suggest for sending laptop to service solution. I have to fix this in *1-2 days* and the service is so far from me and they work slow. If I send to service, I won't take the laptop for 2 weeks.

What can I do, What is the working procedure? If toshiba allow us to update bios, they must support for recovering it, too. ASP is not a solution for everytime.

*Any help* will be appreciated.

Best Regards.

Answer:Satellite U400 BIOS 4.0 doesn't work - error 120

What is the exact model number of your Satellite U400?

I have checked the Toshiba website and I can find different model numbers of Satellite U400 so I think not every BIOS is compatible with every U400.

So check the Toshiba website again and choose your model on the list: => Support & Downloads => Download Drivers
Notebook => Satellite => Satellite U Series => Satellite U400 => (*Short Model No*)

Answer:Satellite U400-18E (PSU44E) - Searching for original BIOS file

Hi pkerk,

Why the BIOS update crashed and why you did an update?

Anyway, everything what you can download on Toshiba website is newest BIOS version with Windows based update program. I never saw other BIOS versions only and it would be useless because newest version is most stable and fixes the most problems.

Maybe you can get the original BIOS file from an authorized service provider so get in contact with the guys.
Normally they can also reflash the ROM module for you because they have professional tools. :)

Dear All,

I was trying for long time to upgrade my favorite laptop's bios....Toshiba Satellite U400-112 (PSU40E)
I have Windows 7 Ultimate (64bit) English and bios version 4.00(until yesterday).
The problem was that in both windows 7(32 & 64bit) the flash tool never started the update process due to several incompatibilities.
There is a solution(actually a work-around) to be honest and works 100%!!!!

My solution is:

A) Download the latest bios upgrade version suited for your laptop,save it (tomake it easier in root of drive C:\) and unzip it to a temp folder(for example: bios).

B) Use the Hiren's Boot CD from an actual CD media or from a USB stick(Download it and burn a CD or follow the process of copying the CD onto a USB stick).

C) Boot the laptop from the CD or USB flash and in the Boot Menu of Hiren's,select the Mini-Windows XP version.

D) Let the Windows XP boot completely and then run the bios update flash tool from the temp folder. Do the update procedure exactly as it is decribed from the bios update manual. (If you are not experienced)

E) It will update the bios and then it will shutdown by itself. Then you can start it normally from your operating system,removing any CD or USB stick mounted on it.

I hope that you will find it useful and handy.

Best Regards,

try to start your notebook using safe mode. Use system restore and roll back the Os to the earlier time. I hope this will help you to start your notebook properly again.
If this will works remove McAfee and install Avira AntiVir. This will make your life much better. This application is really good. Does not need many resources, in just few seconds pick up the updates and does not need to be restarted. I use it for years now and it is, for me, the best one.

Welcome Toshiba,

I've tested this inside out, thats why the statement places in the subject looks like that. After upgrading bios from 3.00 to 3.50 the touchpad looses its accuracy. Its very unpleasant and useless that way.

I tried different drivers, everything, but the only way to really solve this problem was to downgrade it back to 3.00 OR uninstall Synaptics driver completely. Second solution, unfortunately is unacceptable, because then I loose control over a couple features, like click on touch, which I dont use and like.

Best regards


Answer:Satellite U400-PSU40E Synaptics touchpad problem after recent BIOS upgrade

Hi buddy

I?ve got U400 and the BIOS has been updated to the newest one.
The touchpad is working like a dream. I?m using the Vista and Win XP and there are NO troubles after BIOS update!

In your case this can be only a software issue and I think you could use the Toshiba recovery disk and could reinstall the whole OS from the Toshiba disk?

This is a really radical workaround because the whole HDD would be formatted but if the reinstallation of both touchpad drivers didn?t help then I think this would be the last solution.

Maybe you are already using the newest driver.

However, the driver installation can be done from the device manager and it will work if you would use the compatible driver.
But if the newest driver is already installed then you will be not able to update it?. Because it?s already updated ;)

Hi there again!

Now with a new and weird matter.

We all know that old say... "If it is not break, don't fix it". And if you put it into more informatic terms, "specially if it is a BIOS".

Yes, we all know that the BIOS is something quite dellitate to handle. For some reason we normally feel like if we were handling something like nitro-glycerine, or some radioactive product. And this is because we all know what is being put in risk in that moment: our (or sometimes others) computer, the full system could end as dead as some pieces of metal, plastic, and wires.

Well. I passed through all of that more than ten times in my life, and only once it went wrong. But since that old motherboard was already dead, It was not important. But I allways was EXTREMELY care. I allways cross checked everything before doing anything, allways got a backup and a way to restore that backup... and allways did this in COMPAQ systems, that were prepared that way. Updating a BIOS was just about preparing a disk, turn on the PC with the disk in the diskette drive, and wait. And if you didn't like the results, you simply click "return to previus BIOS" and that was it... very nice. And easy.

Few days ago, a friend brought me a Toshiba Satellite 1410-604 to solve some issues that were driving him crazy. After removing an expired Norton Internet Security, install avast and scan, I found more than one hundred files infected with a wide variety of virus, malware, t... Read more

Answer:Satellite 1410-604 - BIOS update > Incorrect BIOS update in the web?

Hi Fenix,

wow... it tooked very long time to read your post....

Maybe I can help you.

The Bios in the Web is the right one. So you have downloaded the correct version of the Bios.

The Askiris you have used is from Toshiba America which has most times not the exact models as Toshiba Europe.
That should be the reason, why the readme does not contain the European modelname.

I would try to make a fresh Bios update using the traditional Bios update.

Copy the files to the diskette, put it into the FDD, press and hold the Tab key while power on the notebook.
After the notebook has shut down, press and hold the key on the left side of the space-bar while power on the notebook again and wait until it powers off again.

If your notebook does not power on anymore, maybe the RAM is defect?

So, if the use of the traditional Bios and/or changing the memory does not help and your notebook is still dead you should go to an ASP, but this will cost money.

I have my fourth Toshiba notebook now and I had never problems with the Bios updates.

The 1410 is very old I think, so before going to an ASP, I would buy a new one ;)

Answer:Bios update gone wrong

Flashing your BIOS is what you where doing. Depending on your system you may be able to use the Boot CD to restore the BIOS to it's factory default. If your PC is older then you will need to contact the manufacture (or a local non big box repair shop) and get a new BIOS ROM chip.

Hi, i was wondering if anyone had any advice.

Last night i updated my bios (ASUS M2N4-SLI), unfortunately during the update the power went off in the house when i boot now nothing happens, the keyboard and mouse are not even booting. There is power to the motherboard but i can?t get a boot screen or anything, is there any way that i can sort this out?

many thanks


Answer:BIOS update went wrong, need help please

Unfortunately there is little you can do if the flashing has failed. If the motherboard does not POST, you are most-likely looking at a paperweight. There may be a bit of hope if your mainboard has a chip socket (meaning you can physically pull the BIOS chip) but most are soldered right to the PCB. If you can remove the BIOS chip, you can send it to BIOSMAN where they will replace it and reflash the corrupt chip. I've used them before, it's a very good service.

As far as soldered goes, I'm afraid that's tough luck. Replace the motherboard.

Question: wrong bios update

I have an acer aspire xc-603 which had the newest bios update for my model p11-b2.  I acidently updated my bios to version p11-b4 which is intended for the aspire xc-603G.  How would I remedy this?  flash the bios again with the original p11-b2 version?

Go to Solution.

Answer:wrong bios update

if the flasher let you revert to a previous version, yes, try it.(not always the best thing to do, reverting to a previous BIOS version) if not and your system is stable, i would leave it as it is.

Well I've seriously stuffed up, I'll give you the long story so you get all the information

Well after I installed my 8800GT, I began having stuttering problems with a game, ut2004. Others had the problem and most say its a driver issue and will be fixed in the future, someone wrote to nvidia support and they suggested updating bios, chipset and getting a patch for the game, so I updated the chipset, 945p, easy then I went to update the bios, after downloading bios 3.7, a command prompt came up with lots of settings and commands and warnings, so I decided I'd play it safe and just do the msi live update. So I installed the msi update and its first update was to update my bios, as it finished it restarted my computer, everything seemed fine until my computer wouldn't go past the original POST page, the one with the motherboard logo on it. No beeps sounded and pressing tab or del opened a black page that says

AMIBIOS (C) 2005 American Megatrends, Inc

The page also has a live update symbol on the top right corner.

I have a hunch that the live update fed me the wrong bios, and thats why the computer won't boot. I dont have a floppy and putting my windows or motherboard cd in doesnt do a thing. Restarting doesnt and turning off and on doesnt. I have limited my options ... Read more

Hello,This is my first time on a forum and I have no idea what "location" to select for this type of issue.  I will try to make this short and simple.  There were a bunch of updates from HP, one of which was a Bios update.  A bunch of others had issues updating.  Ever since then, my wifi keeps dropping, when my service and all other devices are fine.  I try to restart and it hangs there for hours, so I have to hold the power button to shut it off and turn it back on.  When I close my notebook, it will not go to sleep, hibernate or anything I set it to.  Instead it shuts the screen off, hard drive sounds as if it is still running and the computer heats up and power button light stays on.  Again, I have to hold the power button do shut it off.  I have a Windows 10 HP 14 Pavillion was advertised as windows 10 ready, so I don't think it is that since I did that update in July and this just started happening after the bios update.  Is anyone else having the same issues?  Any suggestions to anyone who may have resolved them?  

Answer:bios update gone wrong

 You could try a BIOS rollback to previous version.  1-Immediately after powering on start tapping the Esc key.2-When the menu appears, tap F2 for System Diagnostics.3-In the list of items will be BIOS or Firmware Management.Use the arrow key to move down & highlight it.Press Enter key.4-You should now have a Rollback BIOS option.Use arrow key again to highlight and press Enter key.

I bought a new dv7t quad edition HP laptop recently. I moved the 750gb 7200rpm hard drive to the secondary slot and was using a Crucial 256gb solid state drive as the boot drive. The HP help center told me that I needed a BIOS update, so I let it do its thing, and soon I had a laptop that would show nothing but a blank screen. I called HP and they said it was the hard drive, so I switched them and I have a working computer again. However, I need to be able to switch back to the solid state drive.How do I get rid of whatever the BIOS update did to the hard drive?If you need me to post more info about the laptop, I can.Thank you for your time.

Answer:Bios update gone wrong

I made the leap forward to SSD with 2 laptops and 1 desktop. I had to prep my one OCZ Agility 90GB prior to OS installation, but my system would boot up past the post diagnostics with just an error of No OS Found. The Toshiba System Restore utility would boot and come up with No Hard Drives Detected  as for it was having a hard time finding the SSD and only option was to exit the system restore.So your not getting a successful post ( HP Logo or detailed boot stats )?I'd perform the flash to the BIOS with the original hard drive installed. If the BIOS is already at the version you are trying to flash it to, it wont hurt the computer and it will probably show a screen that shows existing BIOS Flash Version and the Flash version to be applied. If they both match you can exit the flash process as for you are already at the latest version.*The prep that I had to perform to my SSD was that I had to connect it through a SATA to USB cable and make it act as an external hard drive. I then created a NTFS partition on it and then formatted it using Windows 7, which my Laptops OS is, and then I was then able to install the SSD to my laptop, and then boot off of my USB stick to install the OS to the SSD using the Toshiba System Restore Utility that I made before yanking the original hard drive. The restore utility now was able to find the SSD and install properly. This installation process deletes the partition I made when prepping the drive as for Windows 7 wants its default st...

hello there recently i was working on a computer as a favor for someone. He told me he couldn't get on the internet and had some malware so i cleaned out the malware and started to update his drivers from the Hp website by the way it is a Hp pavilion a6412p with windows 7 32 bit. While updating the drivers i noticed an update for bios i preceded to download and install it after being prompted to restart i couldn't get back onto windows ever time the loading screen comes up for windows 7 it just restarts. So i tried to load it in safe mode but the same thing happens were it just restarts and i even tried to load it in last good known configuration but that doesn't seem to work. usually i would just reformat the disk but he runs his business from this computer so that is out of the question and i forgot to make a backup since i thought this was gonna be an easy job so i messed up big time. Any help would be appreciated.

Answer:Bios Update went wrong

Well, at least you did not brick the computer because it looks like you can start loading Windows. Can you access BIOS at startup? If you can, the BIOS update probably worked.

You can download the Windows Recovery Disk and burn the iso with something like Imgburn. Boot the CD and try to do a Startup Repair.

HELP - just updated BIOS, and PC re-started and seems to have given me fresh win7, with no access to files on desktop.
Luckily most files were backed-up to another HDD several weeks ago, but as I wasn't expecting this, I have lost plenty.
Any ideas how to recover, my files and previous windows setup?
Bearing in mind that I don't believe the HDD was wiped as it all happened very quickly.

Answer:BIOS update gone wrong

That does not sound like a bios issue. It sounds like something went wrong with Windows 7, or the drive is going bad.

Download Xubuntu 14.04 and burn the .iso to a DVD. Then run as a LiveDVD, to see if it shows with gparted, the Windows partitions, and files in them.

There is also another question: the "FN" button does not work before what has happened to the BOIS.

Waiting for your help.

Answer:Wrong BIOS driver on my Satellite P200 (PSPBG)


I?m afraid I didn?t understand your issue exactly.

You said you have downloaded a wrong BIOS driver?! ?:|
I assume you mean the BIOS.

The Toshiba European page provides BIOS for the Satellite P200 (PSPBG).
I?ve checked the driver page and at this time the BIOS version 1.70-WIN is available which was released on 13/09/07

This package contains a setup.exe. You can start the BIOS update executing this file.
But please ensure the following:

- Notebook is undocked.
- Notebook is connected to the mains.
- Notebook must be in boot mode and not resume mode.
- Remove any PC Cards.

That?s very important to ensure that the BIOS update would function.

After kids have used laptop when logging into BIOS password I get "invalid Password" I don't think they been into BIOS and changed it, so the only thing I can think of is the language has been changed.

I've had this before but have always managed to log in.
Is it possible from XP to change the key board layout?

If so to what?

Is there a work round, or is it about ?150 repair.

Thanks for looking in.

Answer:Wrong BIOS Password at start-up on Satellite A series


The keyboard language layout can be changed in Windows XP.
For that you have to go to
control panel -> Regional and languages Options -> Languages tab -> details
There you can set an additional or new keyboard language.
You can also use a short key SHIFT+ALT to switch between the languages.

But the main point is that this settings work only while running Windows XP OS.
In BIOS the layout couldn?t be changed...
So it?s hard to believe that the kids changed the keyboard layout?.

For me it?s not explainable why the BIOS password has been changed or why wrong BIOS message appears?

However, if you are not able to boot the notebook due to the BIOS password then you will have to contact the ASP in your country for BIOS remove?
You will have to pay for this service but I don?t believe that it?s expensive?

I?m sorry to say it but it seems you have no choice?.
You have to ask the authorizes service partner in your country for an help? as far as I know the BIOS update mistakes are not covered by any warranty and you will have to pay a little tax for the fixing.

In worse case the motherboard must be replaced? :( but maybe you have a lucky escape and only the ROM chip must be flashed again?

hi --

i'm trying to fix my parents' pc (a gateway 507gr) which has been really unstable & unreliable for a few months. windows wouldn't boot properly, windows reinstalls wouldn't work. it'd boot into the bios ok, but that was about it.

in desperation yesterday, i decided to upgrade the bios, hoping to have a good foundation for reinstalling other stuff. i downloaded the files from intel's site (the board's a d915gag, with a p4 processor with hyperthreading), and did exactly what it said. now things are far worse than before.

intel gave several sets of directions for flashing the bios. the least invasive was to make a cd with this bootable .iso file, put it in the cd drive of the target pc, and boot it up. it did boot under that scenario, but instead of anything resembling the screenshots they showed in the instructions, it said something about the old bios id number, the new bios having a different number, and trying to install it, and then it went immediately to a c: prompt. for a few moments, the pc made these really quiet noises -- not hd sounds, but something somewhat similar (almost like sci-fi "electronic" sounds), but nothing ever happened. it wouldn't even boot into the bios after that.

another method intel gave for flashing was to download & copy this .bio file to a cd, put in into the drive of the target machine, and boot it up with the bios configuration jumper off, to force it into recov... Read more

Hi All,Yesterday reinstalled win 7 x86 on my X61s and initiated a BIOS upgrade after system update asked me to... I am not sure to which version it was attempting to upgrade from and to however it failed, it go to the step of "Reading old BIOS" after which the update utility software just started stalling and became unresponsive. After this my laptop now wont boot, i can push the power button and get a green power light but thats it. I have gathered from reading around different forums that a failed BIOS update may mean a bricked laptop and that this is seen before on windows 7 (does anyone know if this has been confirmed by Lenovo?)Just wanted to check if there are any possibilities for this laptop to come back to life? are there any type of special restoration i can force when powering on? Or do i have any other options? Oh and it is out of warranty. Any advice would be greatly appreciated. Thank you.

Answer:X61s BIOS update gone wrong.

about the only thing you can try is unhook the power supply, take out the battery, find the CMOS battery, (probably under the keyboard), take it out, push the power button and hold it down to drain any residual power in the machine, let it set for about 10 minutes then reconnect the CMOS battery and put the power supply back on and put the battery in and turn it on and hope for the best.  if it still doesn't work, then you'll either need a new motherboard or you'll have to find somebody who can solder a new bios chip on the board, good luck.

Hi All ! Excuse my poor english because i'm french.

A friend gives me his Notebook (a Satellite 4090CDS exactly) because he had a probleme.
In fact, the problem is that when I switch on the computer, i have one and only one message(not even the red toshiba logo) which is "Ready for BIOS update. Place the BIOS update diskette in the drive, and press any key when ready to proceed."

So I go on french toshiba website, in the BIOS download, i find that i have to download this update:

Ok, i download and unzip it to a diskette and i boot the notebook with the disjette, it said that the update was made successfully and automatically reboot.
This time, the red toshiba logo appears, but next i have a black screen with a message:

**** Bad check sum (CMOS) ****
Check system. Then press [F1] key.

And after that, i can't do anything, not even press F1. If i reboot the notebook, i meet myself one more time with the first message "Ready for BIOS update..." and it is still and still the same.

If anyone could help me to understand what is the problem, it would be very nice.


Answer:Satellite 4090 BIOS issue - "Ready for BIOS update..." message appears

It sounds as if your CMOS chip has a problem. It?s possible that the CMOS battery has failed and your BIOS settings are being lost.
Maybe the RTC battery is empty. In this case you should plug the AC adaptor to charge the RTC battery.
Please note that the RTC battery (CMOS battery) will charge after the notebook main battery was fully charged. In this case the charging procedure could take several hours.

But if after this long charging procedure this message appears again so I assume the battery is dead.
I suggest you contact your nearest ASP to get your notebook checked.

Answer:Satellite 5205 - After Bios update - Serviceman / Call Bios message

Hi Jim,

Unfortunately removing the battery will not reset your BIOS. The BIOS is maintained by a separate battery on your motherboard (the CMOS or RTC battery) and you will need to dismantle your notebook to access this battery. Even removing the CMOS battery will not reset your BIOS since it will be held in a non-volatile area of the CMOS chip.

You will need to take your notebook to a Toshiba Authorised Service Agent to have the chip reflashed with a new BIOS.
