Re: Lenovo Legion S7 15ACH6
I've got the same machine but SN: pf2rr6qf
It is currently bricked and doesn't even spin up the fans. (unplugged & died 1/2 way through a bios update!) I'm using a programmer to flash it off-board, then re-soldering it.
While I DO want a working bios obviously, I also would be very happy to be pointed at what I would need to be able to work with this stuff myself; I hate asking people to do things I should be doing for myself. The bios in this one is apparently compiled is my understanding? That seems to be where I'm getting hung up. I'm having a real B of a time figuring out how to decompile it in order to work with it. INNOS Extractor and several walk-throughs have not helped me out much; I'm clearly not understanding something or I'm missing a step or something. To add to the fun, Lenovo seems to have pulled all the full bios images off it's website for this and now only offers partials as 'updates' to a working bios. Thanks Lenovo.

Hi! If possible, I need to disable the onboard RAM as it has issues with the solder joints under one or more of the chips.
My customer is not going to want to pay for reballing the onboard RAM or replacing it, so if there is a way to just disable the onboard memory I'm sure they will be ok with it and they can just buy higher capacity slotted RAM.
Thanks.Comment

Hello,
I have a Lenovo Legion S7 15ACH6 that was interrupted during a BIOS update and is now bricked. Symptoms: fans spin, RGB keyboard lights up, but no display/POST.
The BIOS chip is a Gigadevice GD25LR128. I’m using a CH341A with a 1.8 V adapter. In AsProgrammer I selected GD25Q128 (since GD25LR128 isn’t listed) and successfully made a dump (BiosDump2_pf3eg12j.rar).
My understanding is that I’ll need a known good BIOS dump for this exact model, ideally matched to my laptop’s serial number (PF3EG12J), and that the Windows license key/serial should also... -
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... -
