Hi there, how did you read IC from the chip, how you can get the ch341a to support the chip. Thank you!

Hi, I have tried to flash the bios chip.
The chip is detected in NeoProgrammer as GD25LQ128C ( original name 25LR128DSIG )
The bios file is H5CN42W (https://drive.google.com/file/d/1dUQ...ew?usp=sharing) that I extracted using this guide.
https://github.com/tyrng/ExtractLenovoBiosImages-Guide

I have successfully flash the new bios onto the board. But it doesnt change anything, my laptop still stuck with a black screen (keyboard is lit) when being turned on.

So my question is, how do I what the problem is. I was almost pretty sure it is bios corruption, but right now I have no clue...

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.

Hello everyone,
I'm encountering a rather unusual issue. I recently swapped the CPU on my Lenovo Legion 5 Pro 16ACH6H NM-D562 motherboard. The original processor was a Ryzen 5 5600H (code 100-000000296), and I replaced it with a Ryzen 7 5800H, which seems to be an engineering sample (code 100-000000295-40). The BIOS doesn't seem to fully recognize it. The laptop works, but the BIOS doesn't identify it as a Ryzen 7; it only detects the code 100-000000295-40. Is there anyone here who might be able to modify the BIOS so that the CPU is correctly identified?

Thanks a lot.

I'm attaching the dump.

post 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..

I think it won't work because this is a sample.

The notebook is working perfectly fine. However, I've noticed that the BIOS is not correctly identifying the CPU as a Ryzen 7.

Gpu died on my mb so i bought an exact mb second hand.
The board was listed as faulty lid light on, no power button light, black screen and
fans spinning for 20secs then turning off.
So i dll the latest bios file for the mb (gkcn59ww.bin) and flashed it now it does
the same but keeps looping.

Look for hardware problems, it's definitely not the bios.
