Hello everyone,
I’m interested in laptop repair and BIOS programming, and I recently started learning how to use CH341A programmers.
At the moment I’m working on a Lenovo ThinkPad P50 with a Supervisor Password issue, and I hope to learn more here and share my experiences.
Thank you for accepting me into the community!...

Hi, I have a ThinkPad P50 I bought used on eBay, with an invoice from the seller. The seller doesn't know the password, and I need to remove the BIOS password. I have the CH341 flasher purchased from Amazon along with the 8-pin clamp. Can you tell me how to extract the BIOS and then decrypt it?
I also need to identify the correct chip to read.
MB model: bp500 nm-a451 rev 1
