    Ahoy. Unfortunately the links for the T400 are dead.
    Can anyone re-upload it?

    Hi Guys,

    Seek your help regarding my issue with Lenovo B490 Bricked after update BIOS.
    The issue before i updated the BIOS was failed to enter Setup and based on my research that BIOS shortcut key is locked by lenovo(altered).
    Here why i was done before the system bricked.
    1. I tried to update BIOS to latest one from Lenovo website.
    2. New BIOS cannot be installed before i update to advised version.
    3. Download and flash BIOS using MS-DOS, showing flash bar but the result was failed.
    4. Restart the system and it couldn't POST.

    Symptom:
    - LED Power Button: On While then off, Looping.
    - Try to Fn+R: ON more than a second, like 3-5 second, after that On While then off, Looping.
    - Minimum POST w.o memory: Beep No Memory.

    I suspected the issue w. BIOS Corrupted.

    Tried to Recovery BIOS:
    1. Download BIOS latest and advised update by lenovo.
    2. Recovery using Lenovo.Phoenix.Crysis.Tool
    3. On this point i believed the disk i created was completed and able to use.
    4. Fn+R, LED Flashdisk showing read activity like 3-5 second but it turn off and continuing LED On While then off, Looping.

    Based on my finding this system got 3 different BIOS and i also tried used all the BIOS 1 by 1 with result still failed.

    Next action:
    Re-flash BIOS using Flasher tools (Ordered online).
    I'm still not sure what BIOS file need to flash when the tools arrived, New BIOS / else? (Please suggest)

    Seek ur help or for any suggesting for my issue to solved my problem.

    Thanks !

    It worked. Not exactly as described in the supplied instruction though.

    I used this version
    Instruction tells to flash same version of original bios first and after reboot use the patched one. When attempting to flash patched version afterwards I only had a message that bios version is the same, flashing is not needed and will not continue. I googled a little and found that some guys tried running WINUPTP.EXE -s. So I tried. For a few minutes mouse pointer was lagging badly while updater performed it's job without any messages or windows. Then lagging stopped and after a few more minutes and a check for running processes in Task Manager just to be safe, I shut down Windows, plugged in wifi module, turned the laptop on and it started flawlessly.

    Thank you for your work and for the quick response ! :good3:
