Hello. I'm not very good at English, so I'm using a translator to ask my question. I currently have a LEGION5 PRO 16ACH6H (LEGION5P-82JQ). One day, the power button started working, but the keyboard light didn't turn on, and the system wouldn't boot properly. When the keyboard light came on, it booted properly. I thought there was a problem with the BIOS, so I purchased a ROMWrite CH314A and tried to get it to work. I backed up the information, but it didn't work properly with the data I obtained from there. Is there a way to get the BIOS?
The existing BIOS is gkcn65ww, and 20250807.ZIP is the version I backed up from my device. The JQ below is the version found here.
I'm trying to upgrade to the more stable GKCN60WW version, even though it's a lower version.
But I couldn't find the BIN for version 65...
I need your help.Comment

Attached is a macro script to copy the DMI (serial number etc) from your backup to a new bios. You can use GKCN60WW from your post or GKCN65WW from this post - https://www.badcaps.net/forum/troubl...00#post3682000
Read the attached README.txt for instructions, and leave feedback if it works ok.Comment

Thank you so much for your help.
I think the macro you created automatically saved the data after comparing it to the newBIOS file.
I'll have to try putting it on my laptop.
I'll try that and get back to you.
It's so late in Korea that I left my laptop at the office.
Thank you! I'll get back to you.Comment

Thread merged..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread.
You might find a working bios in this topic.
Post the serial number next time, it`s required with every bios request

It took a long time.
Thank you.
Based on the information you sent, the BIOS seems to be functioning normally.
However, I recently learned that there may have been a BIOS issue as well.
Actually, it seems to be a cold soldering issue in the CPU or somewhere else.
Sometimes the power turns on properly, but then it doesn't.
It seems to work about once out of ten times.
I think it's the "black screen not working" issue that's been trending on Reddit. I understand this symptom is something like a cold soldering issue in the CPU.
Thank you for your help.
It took a long time to identify this symptom.Comment

Hi all,
I acquired a 16ach6h from a friend who was getting rid, and while the power button illuminates none of the fans etc spin up. I've attached a backup of the bios here, and tried to write a 'fixed' version from another of the threads on Badcaps - but keep getting the error 'file too large for IC' in Asprogrammer, neoprogrammer etc. Would anyone be able to help? I've tried following guides to shorten the .BIN file, but the backup comes to 2048KB and the downloaded one works out at 16384KB. I think the backup is messed up, but in any case I'd appreciate some advice!

Hi, can someone please help me with the Lenovo Legion 5 Pro 16ACH6H BIOS bin? The problem is a black screen; the power switch LED is on, the keyboard lights up briefly, and the fans, GPU, and CPU function typically.

Hi everyone,
My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
Laptop stopped booting entirely.
I used a CH341A programmer to dump the corrupted 16MB BIOS.
i then attempted the following:- Downloaded stock BIOS BHCN39WW from Lenovo
- Trimmed it to 16MB
- Extracted the BIOS region from the corrupted dump
- Extracted the BIOS region from the stock 39WW
- Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
- Injected back my LDGB / DMI

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... -
