I’m looking for the original BIOS file for this model, but it seems that others have already tried fixing it.

I have tried all the BIOS files from PKBIOSFIX. With some files, the display comes on, but with others, the laptop does not fully power on.

The original BIOS had a restart problem as well.

Serial number?
 
This BIOS file didn’t work either. The DC power consumption stays between 0.060A and 0.130A, and sometimes it gives a long beep sound.
 
Hello Admin, could you please check my case and reply when possible? I have already tried all the available BIOS files, but none of them work properly. I really need the correct/original BIOS backup for this board. Please help me with this issue.

The BIOS backup I have is not original. It looks like someone else has already tried to fix or modify it, so I don’t have a confirmed working original BIOS backup.

The BIOS file you have that boots into Windows but restarts after some time—could you please fix that one? It seems to be the closest to working.
