Thank you for your responce.
How do you think, maybe there is some method to read this chip?
Maybe some information from datasheet can be useful?
Because this method i think can be useful for others.
Looks like a chip W25Q256JW is similar to W74M25JW....Last edited by zhekanchique; 04-24-2023, 01:04 AM.Leave a comment:

I don't know. I was told that this is not a warranty case.
So why doesn't it heal itself?
Maybe I need to press some key combination? I tried Fn+R, Win+R, Fn+B and much more but no effects.
Sometimes, when i reconnecting RAM, ROM, Wireless card and then turn on the laptop appears LEDs blinking. Videohow it blinking. Sorry for upside down video. It's hard to catch this blinking

Re: Lenovo ThinkPad L15 Gen 3 (type 21C7, 21C8) BIOS Needed
I found one. It is the WINBOND W74M25JWEIQ. But the Programmer can't recognize this chip and there is no such model in XGPro....Leave a comment:

Thanks for your answer. I use XGecu T48 with XGPro 12.55.
Where I can take a clean image? On lenovo website firmware are only files .FL1 and .FL2. There is no .bin or .rom files.
2nd comment is dump from "broken" laptop (in this state I took it).
Thanks....Leave a comment:

Lenovo ThinkPad L15 Gen 3 (type 21C7, 21C8) BIOS Needed
Hi all!
Need bios for this model
[B]Lenovo ThinkPad L15 Gen 3 (type 21C7, 21C8)[/B] Laptops (ThinkPad) - Type 21C7
Serial Number: [B]PW04FZBA[/B]

The problem is laptop won't to start. Some man wanted to do BIOS update, and in some time it crashed and turned off.
Playing with "bottom button", disconnect/connect battery/cmos...Last edited by SMDFlea; 03-22-2023, 03:23 AM. -
