    Lenovo B490 (20205) LB49A Keyboard Problem

    1. Laptop Bios Password Locked
    2. Some one Programmed Bios to unlock ===> unlocked
    3. He Programmed with different version. Original: H9ET82IT but programmed is H9ET83WW.
    4. Problem Started here KB is working well within Bios but not working even in DOS (some keys working with different behaviors also none of Alpha Numeric keys working)
    5. Then reprogrammed again H9ET82IT the same Problem
    6. Tried different versions such as H9ET90TO the Same Problem

    the problem not only in internal keyboard also in external keyboard(USB)

    Board: Lenovo B490 LB49A MB 12208-1 48.4WZ01.011

    Can anyone provide Solution and Bios( Some China Sites such as Chinafix, vinafix have these bios but i have no credits to download from them)

    Note: the mentioned bios H9ET82IT & 90TO works in the same model other laptops

    Sorry for the lengthy description

                                  Hi, my laptop suddenly shut down while it was running. When I try to turn it back on, the screen stays black and it emits a melodic beep.

                                  I used Lenovo's SmartBeep decoder and it returned error 0284:
                                  "TCG-compliant functionality-related error (possibly BIOS code validation failure)"



                                  I then tried to enter crisis BIOS recovery mode by pressing Fn + R at boot. The melodic error code changes, but nothing else happens regardless of whether a USB is inserted. I receive another...

                                  Problem with PANASONIC CF53 laptop after changing BIOS settings
                                  by AquaMan Ua
                                  Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

                                  by jendkkd jeje
                                  So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

                                  I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...
