    My Qosmio x 500 has worked (from the point of view of cooling), until I made a very big mistake.

    This BIOS downgrade option you want to say is not possible as on Toshiba site only the most recent version can be downloaded. Latest version of BIOS is also the most stable version if BIOS downgrade is not important.
    It is possible to the ASP.

  • Evo 500: how easily Flash of the bios on the computer

    I have trouble understanding how to Flash the bios of the computer, I put up.  Can someone give me a step by step method how?

    Let me offer you some general tips to make the updates to the BIOS...

    Caution: an upgrade of BIOS defective or broken, unlike an upgrade of the driver, can leave your PC in an unusable state - essentially, turning it into a "brick" electrick

    Thus, before any update of the BIOS, ensure that the following TWO are met:
    (1) you have a way to save on the current BIOS of some media that allows you then to restore it, if necessary
    (2) you have a way to boot the PC so that you can restore the BIOS since the recorded media, in which case the BIOS update fails or trashes otherwise your PC

    So, as long as the application of updated BIOS provides you with a way to do both 1 and 2), then flashing the BIOS is safe, because if the PC are lost, you will be able to rely on 2) to restore the original, working, BIOS.

    In addition, if you do this on a laptop, at least have the power adapter is plugged when you do that.  Not sure how many people try this on battery power that have the battery before the upgrade flash is done!

    Good luck

  • How to get to the BIOS on new XPS 8700?

    How to get to the BIOS on new XPS 8700?

    This is a brand new machine with Win 8.1, a SSD boot drive, etc.

    I need to get in the BIOS so that I can prepare for the recovery with Acronis backup program. This program will generate a recovery disk or flash drive. If my boot drive does not start, I will use the recovery point, but I need to have the BIOS first try to start from that before the C drive.

    Reading messages on the Acronis forum, I heard for the first time on UEFI - I barely understand what it is - but apparently, a replacement for the BIOS?

    Is it likely that my new machine has UEFI rather than a BIOS? and how do to it? Press a function button for the system to start? A person on the Acronis forum suggested to win 8.1 to restart and hold the SHIFT key while doing.

    I do not experiment on my PC unless I am sure it is the right method. This is my 4th Dell-all previous versions came with a manual that could give me the answer to a question like that.

    The "missing manual" is perhaps on the Dell website?

    Joe

    Your system is UEFI.

    As the UEFI systems start very quickly, you start typing (do not hold) F2 as soon as you power on open configuration. Otherwise, it will just start normally from the hard disk.

    Alternatively, you can start to type F12 as soon as you turn on that should give you a start with options menu to boot from the optical drive or USB. Note: To boot from USB FlashDrive bootable is connected before you turn on the system, otherwise it does not appear as an option in the menu of F12.

    See page 82 in the Manual.

  • How to replace the battery of the BIOS on Equium A210

    I have a Toshiba Satellite A210.

    I can boot the system after many powers and stop operations. When finally, starts the need to press F1, and I get a message like: replace the bios battery.

    How can I do?
    Thank you

    Cannot replace the BIOS battery so simply, and this should be done by the only authorized service provider.
    The whole notebook must be dismantled.

    Maybe your BIOS battery must be charged properly. In user manuals, you can find the exact instructions how do.

    Hello

    Using the BIOS based victory you can ONLY update the BIOS to a higher version but not downgrade.
    If you want to downgrade, you will get a message that you already have the latest version of the BIOS installed.

    Downgrade is possible ONLY by using a traditional version of BIOS, but this can be done by the technician.
