ThinkPad x395 attempt at password removal

[rafaellguerra]

Ok here the new file.
It is important to understand that the autopatcher was written for Lenovo Intel CPU, and a hash value must be changed in Lenovo AMD CPU (which I did) everything further described as in the autopachtcher.
Have fun

I hear several beeps (like music) and no image appears.

I try to patch here and the result is same (sounds and no screen)

Thanks Markus1741.

This is correct file. Can you help me ?

Sorry, wrong chip.
The BIOS chip is near the CPU
You uploaded the Thunderbolt chip.
The BIOS chip is UC3 16MB or W25Q128FW...

Thanks Markus1741.

Hi everyone,

I have a Thinkpad x395 (AMD Ryzen).
I tried to disable the BIOS supervisor password, but I failed.
Can you please help me?

I tried the autopatcher but wasn't able to succeed (black screen, beep sounds, fan spin, but no boot).


I attached the dump of the original BIOS

Serial number: PC-1J7DTF


It would be great if anyone could help me.
Thank you :-)

Based on some other threads on this topic, I tried to overwrite 128 bytes with FF in the EC dump starting at 0x0002EF00.
It looks like I found the right place, but just deleting everything seems not to be enough, I get the error: Post process stopped due to bad SVP data.

Any help would be greatly appreciated.

I have a X395 with a BIOS password. Could someone please help me to remove the password?

In case of an E14 Gen3 the password is stored in the EC, so I attach also the EC dump of the X395:
