I do everything as in the video, I click - I enter the bios 2 times, enter the password is disabled, then I need to save F10 (because when I simply reload the bios, I continue to be blocked by the password) Thank you Done

good night master chief Today I tried again...
I bought some metal tweezers and a Windows keyboard
I don't know what I'm doing wrong or what I'm not doing.
If you could leave me a message so I can follow the procedure to the letter, I would greatly appreciate it.

In old Lenovo it was required to qround security chip just before pressing F1 or even during pressing F1, to brick communicTion, so bios don't read password from it.
Maybe try that way.

I also wonder if it is not necessary to ground all 126 127,128 and 1 pin at the same time to ground.

Also some hint here for older Lenovo:

Any proven solution for Lwnovo L14/L15 and NPCE68BPA0DX, maybe bios file if short pins not work?

This happens to me too,
change the timing and start earlier just before backlight and stays short for less time.

Mec16 is difficult
many many tries

I've a T14 NM-C931 rev1. after many tries with no lucky it now show me before the logo also if not shorted:

0271 Check date and time
0188 RFID serialization inform area (or something like that)
2200 machine type and serial number are invalid

( before start to try i disconnected the big battery and also the button one and the check date and time error started for this)

Is this normal so i should still try?
In a post before i read to not short before the backlight, is still valid or with mec 1663 no?
Thanks in advance for any advice
