Satellite C855 - white screen after BIOS update

Hello

I am a beginner user,
I have Satellite C855
Yesterday, I downloaded a 'update BIOS"that was sent to my computer.
Since that my screen is blank, there is a hum in the background.

I have a recovery back up on my external hard drive, but of course, the screen is blank so I don't know how the product.

I think I must have downloaded a model or the update was not compatible.

Hello

White screen do you mean that nothing appears on the screen?
You see the start screen of Toshiba, or if you are able to access the BIOS?

Where this is not possible, try this:
Disconnect the power adapter, remove the battery.
Press and hold the power button for about 30 seconds.
Then connect the two parts (batteries and AC adapter) for the laptop and try to turn on the unit.

In case this would not solve the problem of the laptop, I'm scared of m the BIOS update was not completed successfully and I think that only authorized Toshiba service provider would be able to help you.

  • Satellite C650 - black screen after BIOS update

    My Satellite C650 Windows 7 - won't start afte BIOS update / switch.

    Everything worked very well until the automatic update of Toshiba asked me to download and install the new BIOS update, I did. At the same session Windows and McAfee asked updated. I agreed to all. After all updates have been installed, turns off. The next day when I walk, I see only black screen. I also tried F2, F12 and drive recovery. Nothing happens!

    Any recommendation?

    Hey,.

    It seems that something was wrong during the update of the BIOS and so that you can t the computer unbootable. But I put t understand why you did the BIOS update. If everything works correctly, you can forget about this update. More if you do a BIOS update you shouldn't t run any other updates or programs that might affect the update of the BIOS.

    Anyway, in this case you can do nothing and you need professional help. Please contact an authorized service provider and guys can help you update the ROM module On the Web from Toshiba site, you can find a list of all the FSA:

  • Re: Satellite L40 - black screen after BIOS update

    Hello world

    I have exactly the same problem, as shown here:

    http://forums.computers.Toshiba-euro...ThreadId=35156

    My laptop is a Satellite L40 - 150 (model PSL48E) it came with Vista and BIOS version 1.60

    I updated the BIOS to version 5.50, because I wanted to install Windows XP. The BIOS update process went well and the computer restarted automatically. After the reboot, I entered the BIOS (by pressing the F2 key). I pressed F9 to load the default settings and you exit the BIOS, saving the changes.

    Restarting the laptop and the screen is now completely empty. Nothing appears in it.

    I tried to remove and then reinsert the RAM modules, but it did not help.

    So, I guess the only option is to return the laptop to a service center?

    Why Toshiba do that? They are this deliberately or what?

    Kind regards.

    Hello

    I put t agree with Leolo and put I t too agree with you.
    The point is that there are tow updated BIOS for the L40.
    One for Win XP and one for Win Vista;
    But the two BONES work on with the two BIOS but some functions such as the FN buttons wouldn't work if you n t use good BIOS for the good OS.

    The BIOS on the Toshiba page is not defective. But of course, it is always possible that something will go wrong during the BIOS update procedure because the BISO update is always risky!

    One of my friends has updated the BIOS on this laptop and everything went well!

  • Satellite P300 - white screen after waking from sleep state

    I'm having this problem:
    The LCD screen may be empty when the computer is "awakened" from the sleep state. Nothing is visible on the internal LCD or an external monitor.

    There seems to be a solution:
    An update of the firmware for a component in the main circuit of the computer solves this problem. This update must be performed by an authorized Toshiba (ASP) Service provider. Until arrangements are made for the update, restart the computer by pressing the power on button for a few seconds.

    In fact, I think I'm able to solve myself, and I don't like not my laptop to be gone for two weeks or more. I just need some advice on where to find a correct upgrade. Is - this driver BIOS or graphics? Which version should download, where... etcetera. More tips on how to solve the problem are also welcome.

    If you check the Toshiba document you would see that your Satellite P300 is not related to this issue.

    In your case I would recommend upgrading the BIOS and graphics driver.
    In addition to keep your operating system up-to-date.

    I had this problem under Win XP and a MS patch and an update of the graphics card driver helped solve this problem.

  • Satellite L450 (PSLY0E) - a black screen after BIOS update

    It seems I have "brick" my phone during a bios utdate that went wrong... black screen as suspect: o.

    The laptop is a Toshiba satellite L450 (PSLY0E)
    The new bios image is named "bwaa150a.rom".

    Anyone know if it is possible to recover the bios of the flash or floppy drive, using a sort of toolfrom recovery inside the bios chip?... .or something?

    Anyone know who is the manufacturer of this bios?
    If I rename the bios image during a recovery, what 12xxxxx be named?

    To my knowledge, it is possible to reflash the EPROM module using the special procedure of crisis of the BIOS. But this crisis BIOS disk for Toshiba computers laptops isn't available for download.
    This must be done by authorized maker Toshiba.

    But I also read in the forum about those who tried some discs of crisis 3rd party BIOS.
    Sometimes it worked, but in most cases, you need advanced help technician.

    However, to use the forum search option advanced to search for similar topics on crisis disk BIOS. Otherwise, as I said above: you last chance might be the ASP.

  • Re: Satellite L500D - boot problem after BIOS update

    I downloaded the new version of BIOS (v1.4) official Toshiba site to update my computer Satellite L500D (PSLK0A - 00U009). But after the update, Windows 7 cannot start, Windows logo appears for a while then it restarts automatically. Windows then goes into repair mode. I followed the instructions on the screen to fix. But it does not work.
    When I reinstalled Windows, the computer worked fine until Windows Update told me to restart the computer. The computer dies again.

    I think that this version of BIOS has a problem. I wonder if there is a way to downgrade the BIOS to the earlier version. I found some instructions on the net to use the Phoenix recovery disk, but I have no file disk and BIOS.
    Please Please HELP, very appreciate.

    TKS

    Try to install the OS to help original Toshiba recovery image. After disabling automatic Microsoft updates to install. When you get the message about controlled initially available updates and install important updates only.

    Check it once more to see if the same thing will happen again. Display the results.

  • Satellite Pro P200-15W: after Bios Update 1.90 incredibly noisy fan

    Hi, I have a Toshiba Satellite Pro P200-15W, I recently made an update to BIOS version 1.9 and seems to have been a big mistake.
    After restarting the computer, I had a lot of software deconfig and the fan has become incredibly noisy.

    I have the problem with the Toshiba Vista registration software, I get this message: "registration of Vista has stopped working". I read other discussions, I don't want to just disable it in the start.ini file, I would actually solve the problem if there is a way.

    Is there a way to change the configuration of fans? I read a post from Toshiba on another model of laptop that has had the same problem of noisy fans after an update of the BIOS, they gave that a solution with a new version of the BIOS, is there a way to reverse the BIOS to the previous version? (recovery CD will be useful for this purpose)?

    See you soon

    Edgard

    Hello

    It seems that the picture of the fan was changed and renewed in the new version of BIOS, and so fans run fall.
    Why the table fan has been changed?

    Well, usually something like this is necessary to improve the reduction of the internal temperature while the CPU and GPU are running with maximum performance.
    This helps to prevent the equipment from damage!

    Usually, the recovery CD formats the whole HARD drive (partitions too) and installs only the image of Toshiba on the notebooks of HARD drive.
    The image contains the OS, drivers and additional software and has nothing to do with the BIOS update.
    But you can try to recover the laptop to see if you can solve the problems of software as "Vista record"!

    If you want to reverse the BIOS, you will need to contact the ASP in your country!

    Sorry, but all I can suggest.

    Best regards

  • My Satellite L300-110 hangs after BIOS update

    My Satellite falls down after I updated the BIOS. The old version of my Satellite L300 - 110 (PSLB0E) BIOS was 1.40 and upgrade to 1.50.
    From there on, my system hangs over and over again.

    Any help please. I cannot install Office Enterprise 2007, cannot defragment all my readers.
    Is there an option to restore changes made to my BIOS?
    Help!

    The default settings in the BIOS load after the update?

    You can reinstall Windows with the Toshiba Recovery disk? First back up your data because the HARD drive will be formatted and then start the installation of recovery.

    A restoration to the previous version of the BIOS is not possible, because on the Toshiba site is only the most recent (1.50) BIOS. Only an ASP (authorized service provider) can do a restore.
    You can search for an ASP here:

    I don't know Mr. but you did a backup of the old BIOS? Maybe you can Flash this back.
