Lenovo Legion S7 15ACH6
Serial Number: PF31VQ4K
Motherboard Model: BM5070_V1.4
Edit: Found the On Board RAM Disable script; Fingers crossed that this works.
Edit2: Did not work. All voltage rails are present but CPU and GPU do not get hot. No shorts are present and resistances on all rails are good. Using known good slotted RAM and the fans spin with keyboard lights, but no POST.Last edited by ResoluteHawk; 11-30-2024, 02:10 PM.Comment

I put the BIOS that you posted through the disable RAM script and flashed it; I'm still running into the same problem.
If this script is actually doing what it's supposed to be doing, then I'm likely running into a problem with a dead chipset/APU, but this diagnosis doesn't make sense since all voltage rails are present with good resistances.
CPU and GPU are getting slightly warm but nowhere as hot as they should be for system power on, and the system is running for 5+ minutes. CPU and GPU VCORE voltages are present.
I have no other ideas at this point.Last edited by ResoluteHawk; 12-02-2024, 09:20 AM.Comment

Thanks for the reply.
Just to clarify: this laptop has already been through multiple repair shops, and several different BIOS files have been flashed to it — none of them worked. Unfortunately, in the country I live in, getting access to verified BIOS files is very difficult due to various limitations.
At this point, I'm only looking for a verified, clean BIOS dump that exactly matches my machine:
- Model: Lenovo Legion S7 15ACH6
- Serial Number: PF2XWM03
If you or anyone else has a known-good dump from a working unit of the same model, I would be truly grateful. Honestly, I had given up on this laptop — but today I decided to give it one last try and reach out here for help.
Thanks again for your time and support.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... -

Laptop was powered off during BIOS update. Laptop turns on, keyboards lights up, and then just beeps over and over into infinity until powered off.
Model: Lenovo Legion 5 15ACH6 Type 82JW

Attached is the BIOS dump from the laptop and the latest BIOS update from Lenovo.
I searched and I don't believe this particular bios has been posted. I attempted to the follow directions
on the BIOS guides page but I am brand new to this and the update file doesn't seem to match
the bios dump in size so I am at a loss on what to do to... -
