Lenovo Thinkpad T14s GEN 4 Supervisor Password Bypass

[Andreasandreou]

Hello, I have Lenovo Thinkpad T14s GEN 4 serial number GM-0FK2ER laptop. It was brought to me by a customer to reinstall windows. The problem is it is locked with a superviser password. Can anyone please give instructions on how to reset the bios or bypass the supervisor password? Thank you.

Can you please explain with more detail? What is EC? How can i read it?

EC = Embedded Controller
you can read it with programmer like vertyanov or svod
if i’m not wrong your EC p/n is npcx997

Nope...He has i7-1355U so no solution today... as far as I know...maybe I'm wrong.
NPC997 is for AMD version and works perfectly...

It’s better to check it first EC part number before you buy the programmer

Hello,

I own a Lenovo T14s Gen 4 notebook with an AMD processor. The notebook has a supervisor (BIOS) password. How can I remove this password and what do I need to do that? Could someone perhaps give me a step-by-step explanation of how I could do it?

Thank you in advance.
