if you get errors, you are on the right track,
0188 RFID serialization inform area (or something like that)
2200 machine type and serial number are invalid
you have to keep trying.
start just before the logo and change your timing (more or less long)

After many attempts I was able to enter the bios setup in which only one DATE/TIME entry appeared.
I set the correct time and kept trying but just went back to the same bios menu.

(I am using an external keyboard without disconnecting anything from the motherboard) (only the speaker for the annoying beep)

maxpower very much thanks for this simple method. I was able to remove the SVP of a Thinkpad T590 NM-B901 MEC1633. I actually planned to solve the SVP problem by accessing the JTAG interface. It's just that my programming device (Revelprog IS) doesn't support the JTAG interface.

Hi everyone, I'm having a hard time with understanding what I must short on my particular model (T14 gen 3 AMD). I have a NM-E441 rev1.0 board with NPCX997. I attached the schematics for the board and also photos of it.
I'll be deeply thankful if someone can give me advice.

hello! master chief.. Good night..
I tried again watching the video the "enter password" sign appears then it is deleted (I imagined I pressed ENTER) then the red sign appears (LENOVO) and press F1 to enter bios... and then the PASSWORD logo appears (but this is deleted again)....
Then the red "Lenovo" sign comes back (that's where it hits) but it sticks to me... what am I doing wrong? because I don't know anymore and I've done it many times...
My chip might have something to do with it
