Supervisor password is in EC. Cannot be unlocked in BIOS directly.

How I can direct connect to MEC1633L .
I have from Vertyanov JIG programer, but not have points where connect.

Re: Lenovo ThinkPad T540P LKM-1 SWG2 MB 12308-2 48.4L016.021 PASSWORD

Unfortunately, I could not find any information on the Internet for the T540p model, which points on the board should be used to connect the programmer.
So I had to figure it all out myself and here is my result.

As a programmer, I used the already mentioned JIG from Vertyanov.
Everything worked the first time.
of course I had to have power connected to the laptop.
If you have a motherboard outside, don't forget to connect an additional board with USB and RJ45.
If you do not connect this additional board, your NB will not turn on.

To remove the password in the BIOS, just overwrite the eeprom area in the MEC1633 chip with the attached file.
