Lenovo Thinkbook G4 ABA Bios needed

[trepachka]

Hello, this notebook starts normally: power button lights up, keyboard backlight comes on, I can hear the fans start spinning. However, I get no video on the screen. I assume the bios is corrupted on this computer.

Could someone, please provide a clean bios bin for this computer? I attached the original bin file here. Thank you.

Serial# MP2CJM4T

Hi Peste,

I applied the bios you provided. Computer is doing the same thing except the fan spins for about 3 seconds initially, then stops. The CPU gets hot. Prior to this, the fan would spin continuously.

Could you, please take a look and make appropriate adjustments to the bin file? Thanks.

I have nothing to do, it's a virgin bios, maybe you wrote the bios incorrectly or the laptop has another problem...try to write it one more time..
