Can you help me fix or repair this BIOS?

Lenovo Thinkpad P1 Gen 4 (type 20Y4 ) 213013-1

I tried other BIOS files from this thread, but it only turns on with my bad BIOS. It turns on automatically when I connect the charger, but no picture, not reacting to the power button. Sometimes the ESC, F1, F4 blinks when it turns on from the battery. Nothing happens with other BIOS files, not even turns on.

Thank you!
