Default Re: Lenovo L560 - bios PWD

Dear bad caps community!

I could successfully read/write from my BIOS chip 25q128fvsq to a raspberry pi 3b+ and vice versa using a "8 pin SOIC8 Test Clip" and "6 x female to female jumper wires" (thank you "PA8600: Tech Videos and More").

Unfortunately the provided unlocked bios dumps from mcplslg123 and dr_laptop05 did not work for me. As [email protected] wrote the fan was speeding up and there was a dark screen after flashing the bios chip and pressing the power button.

What steps do I need to do in order to patch my original/backuped bios dump in order to get rid of the annoying supervisor password?

Since I have 3 x lenovo L560 laptops I also plan to exchange the portion of the HEX difference with the other two laptops as soon as I have a working unlocked bios dump from the first laptop.

Please help to save environmental resources...

Many thanks in advance!
