Hello, I also have a similar issue. Upon powering up, computer keyboard lights up, fans begin to spin, both the cpu and gpu get warmer but no post/video. I suspect corrupted bios.
Please, help me fix it.
Model: Legion 5 15ITH6H
S/N: PF37G3TD
Motherboard: NM-C711 REV 2.0
Both BIOS files are attached. Thank you.

Thank you for help. I wrote the files but the symptom is the same (starts, the keyboard is lit and I can control the light from keyboard but no image and no boot). I saw another memory on board, w25q16. Can this be the problem? Where can I find the file for it?Comment

Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered... -

Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
