Thank you for your answer.
Is there no other way than to desolder the chip? Unfortunately I don't have the necessary equipment like the hot air soldering iron and the knowledge to do this.

A WSON8 pogo adapter but they are just as unreliable as the SOP8 clips.

don't use the clip, remove the bios chip from the case before writing or reading..if you don't have something to solder the wires between the programmer and the chip..

You are right. Excuse my stupidity, I'm completely new to the subject.

I think I have found the right chip (winbond 25R256JVEQ).

I connected my ch341-programmer same way like the other chip and tried to detect the chip via neoprogrammer. Unfortunately I only get the message: “IC not responding”.

So unfortunately I am not able to read the BIOS from the chip.
Am I doing something wrong?

You chose the wrong bios chip, 25Q80DVSIG is not a bios chip.

I attached it to ny posting yesterday, was it wrong?

BTW: Problem is an unknown supervisorPW on an used-buy laptop. I tried with lenovo_autopatcher, but it didnt worked....

Hello,

unfortunatly I tried to Restore the Bios without an Verified Backup. I get 3 diffrent Bin files before flshing 25R256JVEN Chip.
Can you help to restore Bios ?
Laptop doesn't do anything only Power LED is on and Laptop restart every 5 seconds.
No Clip used, with one of the bin files Backlight comes up before reboot
