    Lenovo Yoga X380 22LH Supervisor Password removal
    by AppleLover123
    Hey guys,

    have a laptop here that has a supervisor Password (dump in Attachements).
    Before i write the Serial NR.etc i wanted to say that strangely after flashing with 3 different Bios dumps and one from lenovos site
    the laptop works but everytime it wants me to type a supervisor password i never set.
    I thought the supervisor password is stuck in the ec bios but no it isn't either because after replacing the ec chip from one of another board it still has the supervisor password.
    Anyway i wanted to ask what of the two chips is the ec bios because on the left...

    Asus M7600R BIOS Password request/removal
    by Johnny h
    Hello,

    I'm hoping someone can assist me.
    I have an Asus Vivobook 16x Pro OLED laptop which has a BIOS password, and I can't seem to find it.

    The model number is M7600R and serial number is N8N0CX03H71131C.

    I also tried to use *************** MOD EDIT ,redacted************** and it also gave me the funny password of
    Code:
    tmNx\'=QJQ

    I have a Lenovo Thinkpad T14 Gen(intel) that has an supervosr password set, and I need some help removing it. I have a programmer and have read and re-written BIOS chips before, but am not finding any info on how to do this on a T14 Gen 4. Here are the details:
    Thinkpad T14 Gen(intel)
    Model: 21HES40C00
    S/N: PF4HMJJMX

    I can upload the BIOS file as well, but not sure which chip it is, I will post pictures for reference, guessing it is one of these two:
