Hello, I have this ThinkPad P1 Gen 4 that has what I perceive corrupted bios. Computer charges and upon pressing the power button, the keyboard lights up briefly, both fans begin to spin and the cpu gets warm. However, I get no post.

Hi everyone, hope everyone's having a great day.
I have a Lenovo Thinkpad X1 Yoga Gen 3 for repair. (20LES3T900)
I looked in every corner and the laptop seems fine. Its pulling 500mA but no display, no noise, nothing.
So I assume its a BIOS issue. I downloaded the BIOS with CH341A and opened it on ME Analyser and didn't receive any errors.
Does this mean the BIOS is fine? making it a hardware issue?
I downloaded fresh BIIOS from the Lenovo site and used Hex Editor replace the Lenovo's BIOS into my BIOS region. But the file size ended up being...
