How to get down the BIOS

can someone help me please

I want to downgrade the bios

It's the upgrade AIBSYS-00228463-1040. EXE

and I'm looking for the original file that came firs time

Hi azizissa,

We use the term 'Flash' each time that we refer to upgrade or downgrade the BIOS.

Original BIOS can only be flashed to the Sony service center... Sony does not provide the original BIOS download for all models

The version of the BIOS that Sony uses on their computer varies from commercial version... so do not even download a version of BIOS from third-party sites.

You will need to contact the after-sales service.

  • 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?

    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.

    Hi Thomas,

    The normal to access the BIOS path will be to press ESC then F1 during startup. This will give you the BIOS menu. Some laptops use ESC to show the progress of the POST and F2 to enter the BIOS menu.

    F8 will allow you to start in safe mode.

    F12 to select boot device (disk, CD, etc.).

  • How can I access the BIOS on a Pavilion p6710f when the usb keyboard is not recognized during boot?

    There is no connection to access the bios with a standard PS/2 keyboard and the USB driver does not load in time to access the bios with a combination of keys on the keyboard. I need to check the version of the BIOS and check the settings of hardware for my readers who are accessible via the BIOS. If I can't enter the appropriate key, how to enter the BIOS? Seems to be a common problem, since I see issues with some answers all over the internet. I even looked for a possible 'hidden' ps/2 connection in the case, but not joy.

    Have you tried another kbd? I recently saw a poster that is having this problem, & an another usb kbd did the trick for him. FWIW, I have a usb keyboard and mouse, and mine is trying to get into the BIOS.

  • How can I enter the BIOS of a Portege M100?

    I have in fact two problems: How can I get into the Bios and why I can't install the latest drivers for the graphics chip?

    I want to increase the performance of grafic maximally, as I increased the RAM and the laptop is fast enough.
    I would like to play more games requiring directx9c.

    Anything you can help me: tx in advance.

    Hello

    Do you use the Toshiba BIOS or Phoenix BIOS?
    I'm not 100% sure but I think it's a Toshiba BIOS... in this case, you can use the ESC key to access the BIOS settings.

    > I want to increase the graphics performance to the maximum.
    I have bad news for you... the only true way to increase graphics performance is the upgrade to the graphics chip... BUT this is not possible. The GPU chip is fixed on the Board and it is not possible to remove it.

    > I would like to play more games requiring directx9c
    Well, most of the games require the directx9c. You can use the command "dxdiag" to access the DirectX settings and verify the installed version.

    By the way; You can download the directx9c from the Microsoft Web site

  • Cannot get into the bios of the start screen.

    Well I had run into trouble with my video card, and it had to be replaced. Before I do that but I was invited to try a system recovery to get rid of any possible program that was at the origin of defective symptoms of a video card.

    Well, I replaced the video card and everything has been fixed. But... because of the recovery of the system, some of my settings changed in Bios is returned back to default. I remember specifically in the Bios to disable the action keys (Fn + everything related F who did something).

    Problem is now I can't return to the Bios to change the settings once more.

    In order to dispel some of the suggestions more simple I tried already:

    Using another keyboard (allows me to enter the Setup program, reinstall system, diagnostics, etc. very well but not Bios)

    Unplug everything in the back, but the monitor and keyboard

    Erased from the memory CMOS, which led me to a screen saying that my Bios is set by default and to go to the configuration, press F10. But by pressing F10 led me to the single configuration screen and couldn't get into the BIOS.

    I carefully searched the internet to find answers for this problem, but I really hit a dead-end.

    I want to say I know that I've changed before setting on this computer it's just that I don't remember how. I mean I tried F1, F2, Del, Ctrl + Alt, and everything inbetween for shortcut keys enter the BIOS nothing helped.

    Thanks in advance for your reply eagerly to receive a response.

    Oh and I have a HP Pavilion Slimline s5260f, if that helps anything.

    Well fiddle with stuff I have solved my problem. Thing, it's actually, I couldn't have what I wanted through the BIOS screen. I remember he made on my friends computer to get rid of it, where their BIOS had more options.

    As for anyone with my problem (hit accidentally the Fn and the sleep button) I recommend that to go in Control Panel Power Options - then select doing nothing to hit the Sleep button.
