Can someone help with how to set up and read this Lenovo model with a BIOS password using SVOD 4 please

Gotta start shorting early on MEC1663. Listen to the coils whining noise, as soon as you hear it, short pin 8 to GND for 1-2 sec. Before you see any image. I also used external screen with internal disconnected and external keyboard. And use ALT+CTRL+DEL to restart and try over and over. You'll get it eventually.
Also I used a tape to cover every other pin except for #8 to save myself a headache of accidentally shorting 2 pins next to each other.

WHAT IS PIN 8? PLEASE...

Hello, I have a T14 Gen1. I've been trying all day to clear the SV password using pins 4, 6, 8, and 10.
Currently, I only get the startup logo, and after a short while, the laptop shuts down.

Can anyone help me with the best way to do this and get my notebook back up and running?

IT WORKED ON THINKPAD T14 I7-10610U.
The pin order is as follows:

1. Where number 14 is located, that is pin 14. The others in the same line are 12, 10, 8, 6, 4, and 2 (2 is also marked on the motherboard).


2. Where number 13 is located, that is pin 13. The others in the same line are 11, 9, 7, 5, 3, and 1 (1 is also marked on the motherboard).



Procedure:

Use a clip to short pins 8 and 10.

Power on the laptop, hold the short for a moment, then release and press F1.

If the keyboard doesn’t work, use a USB keyboard.

Once inside the BIOS, remove all passwords (leave them blank).

Save the changes and reboot using Ctrl + Alt + Delete.

¿Puede alguien marcar los puntos a tocar en la imagen? Sería más facil de entender, ya que soy principiante.Can anyone mark the dots to touch on in the image? It would be easier to understand, as I am a beginner.

Hi all! First of all I'd like to express my gratitude and appreciation to Maxpower3 for the shorting method which helped me to remove SVP from my T14 Gen1 Intel based laptop. Everything went smoothly - I shorted one of the required pins to ground, disabled SVP and cleaned the security chip (a couple of times) and rebooted by ctrl alt delete. Password is gone. But i stii get the 2204 Error after rebooting from Windows. I tried reinstalling Windows, that didn't help. I used Lenovo Utility flash drive, initialised the EEPROM, rewritten all S/Ns and other ids to EEPROM. But that didn't help as well. I disconnected cmos and main batteries and tried again - same error. Does anyone know what I can do about it? I have a suspicion that it throws this error because I am disabling Security Boot in the Bios settings. I need it to be disabled for Linux installation. I attached some photos of the errors I get. Is there a way to solve this issue? Thanks in advance for your help, it is highly appreciated!

rewrite the notebook's name,It will be OK.

Hello. I just bought one SH laptop, Lenovo Thinkpad T495 and he have password on BIOS and he have something called MDM protection security or something like this.. It's there a way to get rid of that MDM protection? I don't even know what is that MDM... a hardware component, software thing. Just to be clear, i cannot return the product because i bought it from a ( i don't know how to say ) like a car boot sale, a place where people come and sell thing and it's possible to never see those people again, so, i can exclude the return option. Thank you !

now on every boot up I'm getting error 0183: Bad CRC of Security Settings in EFI variable. Press F1 to enter Setup. Then if I press F1 it asks me for a supervisor password. I can't get pass this and boot or go into bios anymore. e.

Have you tried removing all power sources including CMOS battery and holding the reset switch for 60 sec?
