Lenovo Legion Pro NM-D562 Rev. 3.0

[T-PDF]

Hey guys, i'm curently trying to repair the laptop of my uncle, here is the deal, when plugged : a short press will do nothing, but a long one does (2-3s),--> keyboard turns on for 5 secs after de click then turns off, -->Power button led stays yellowish and nothing on the screen and for the fans, it depends but most of the time, no fans.
So i'm guessing a bios fault but i'm not sure, haven't check the voltages yet.
Also when plugged : Orange led on the charging port and Legion logo on as well. (even after overnight recharge)

Specs :
Bios Chip Name : winbond 74M12JWSIQ 2137
Laptop name : Legion 5 Pro-16ACH6H Laptop (Lenovo) - Type 82JQ
S/N : PF3AQ5K2
MotherBoard : NM-D562 rev: 3.0

AMD Ryzen 7 5800H 16 Go SSD 1 To 16" LED QHD 165 Hz NVIDIA GeForce RTX 3070 8 Go Wi-Fi AX/Bluetooth Windows 10 Famille 64 bits

i've tried to reflash the bios with an CH341B, but nothing seems to work, i've even tried a bios from this forum (that matched the Motherboard rev: 3.0) and still the same results.

If some one could send me an trusted .bin, i'll try and get back to you. Otherwise i'll inspect my motherboard in details.

CPU and GPU are getting warm when charging.

Any help would be much appricated, thx in advance.

The BIOS from post 5 worked for me, however, I should mention that it didn't work the first time I turned it on. I forgot to turn off the device, and after 2-3 hours, it turned on by itself

Hello everyone, I have a Lenovo Legion 5 here, and after turning it on, only the power LED lights up. Sometimes the keyboard backlight comes on, but not always. I suspect that the BIOS is corrupted or something went wrong during an update. I have extracted the BIOS and am sending it here. Could someone provide me with the correct BIOS? Thank you very much.
