volinakis I used yours (I assumed the other one uses the same mechanism).

nope, the other one doesn't even have NVRAM volume cleaned. I am sure it will not work.

volinakis franklinogot The patched bios worked like a charm, I did not even have to remove the winbond chip (I used clips), clean & quick method. Thank you very much! :-)

which patch did you use? mine or the other one? because they are different.

volinakis I also have a t495s laptop with a supervisor password set (I know this thread is for X395, but it's the same motherboard).

Can you please patch the attached bios dump for me so that I can try your method? S/N PC-1HF898

Thanks.

Hello everyone.
I am new member Mitolamito.
I would like to offer my one tip on this issue that has been stagnant for 5 months now.

I am a Thinkpad X395 user with Bios Lock applied.

I have been trying to unlock this ThinkPad for about 2 weeks now, but have been unable to solve the problem.

The tools I used are.
Lenovo auto patcher
Uefi Play-ground
HxD
Uefitool... etc.

Today I decided to edit the EC chip and give up if it doesn't work.
Since I was in the middle of the last work, I removed the Cmos battery and wrote the original BIOS back to the chip.

Then what do you think? Instead of the dreaded key symbol, the Entering Setup.... appeared on the screen. Fortunately, I was able to enter the BIOS.
Immediately I turned off all BIOS passwords, rebooted, and successfully launched Windows 11!

However, this was a complete coincidence. In fact, I had no idea what I had just done to bring about this result.

More however, one thing is for sure: there is possible that you can also unlock BIOS of X395 without an EC programmer like Vertyanov.
I did not use an EC programmer this time.

I'm tired of typing long sentences, so I'll stop here first.
In my next reply, I will itemize the main tasks I did.

the same problem

[volinakis]

so, patched file worked and you were able to unlock it. And when you put back original file laptop doesn't turn on, right? Check soldering and if your chipset is MX25L128 change it with a winbond W25Q128.
