Re: lenovo thinkpad P50

I tried, there's no video card.
I have 0.9v on video card coils. But there's no nvidia in device manager, gpu-z etc.
The laptop looks like new.

There is nothing left to edit in the bios, chances are you have a hardware problem.

Re: lenovo thinkpad P50

Hello Forum, i have this machine:
Lenovo P50 TYPE 20EQ-S1PN00 S/N PC-0QWK7X
MB BP500 NM-A451 REV 1.0
The problem is that the display won't turn on and I think it's a bios problem.
Not even an external monitor.
The problem appeared after I modified some "graphic adapter settings" in the bios menu. Please, can you give me some help?

This is my original dump
