L15 Gen 4 Supervisor PW reset

[Robin Dieker]

Hi

I have a problem I want to reinstall win11 on my laptop but I set a supervisor password which I forgot so I couldnt get into the boot menu. I then tried to enter my "standard" Passwords but now it just tells me that i am locked out and a superuser password is required and that I should press F1 to enter setup. Unfortunately I havent registered my Fingerprint with it.

Any way to reset the supervisor password without contacting lenovo? I have seen some kind of usb device however I think I would need access to the BIOS to flash it, right?

Thanks

If you need info;

Serial PW-09S0V1
Model 21H4S9FK00
Type 21H4-S9FX00

Thanks!

No you must take out the board and look some nr on it
also look what the SIO chip is
