If I remove the PQW1 MOSFET, the 19V rail starts working, and I can turn on the unit - at least I get the fans, and the power light comes on, when I simulate the power button being pressed. No display.

Dear all,
I forgot my BIOS password of my Surface Pro 3, I searched for solutions for a long time and knew that by using FPT to dump my bios to bin file and using decryptor, I can get my BIOS password.
Now I have a problem that I am unable to dump my BIOS into bin file.
My Surface Pro 3 currently runs on Ubuntu 22.04, with Secure Boot enabled and Boot From SSD Only.
I searched for FPT but there is no Linux version and none of them work.
I hereby request a copy of Intel Flash Programming Tool for Linux x64.
I would really appreciate it if anyone...Yesterday, 11:18 PM -
