I know, I used the NeoProgrammer for the back-up, but I already flashed another bios to the chip, and now I do not have anymore the original one

I can give you the file from the Lenovo homepage, but it doesn't have the DMI since you don't have the original file.

I am using a cheap CH341A programmer, and I do not have any backup. Do I have any chance to bring the laptop back to life again?

CH341A has at least 3 software support.

I tried 2 dumps: e8cn41ww and NM-C821 DUMP obtained from this site but without success. The laptop behaves the same with both.
The only option left was to try a virgin BIOS dump, also downloaded from this site. However, I can't try many dumps, as I can damage the board or chip by successive soldering and unsoldering.

you have everything you need at post #204...

I've done something like this before, but I don't know why the information wasn't read correctly, or that's how the information was, I don't know. Now, the deed is done, I have nothing to do, maybe someone can help me with a suitable dump. I've never had anything like this before, I've previously solved problems with BIOS and firmware on TVs and coffee makers. The programmer I worked with is EZP2019+, in my opinion it's no better than CH341A.

The original dump file is compromised in my opinion. I checked it with a hex editor and most of it is with FF.

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

here is a video for example..https://www.youtube.com/watch?v=DWWi...l=ThisIsHow
