He charges only $20 for bios master password and support until your bios is unlocked. Unlock your bios or your money back guaranteed.

  2. No need for a mastermind if you want to unlock an administrator password protected BIOS of a Dell Precision T3500.
    Just draw the PSWD-Jumper in the middle of the mainboard.
    FYI : Removing the coin cell does NOT unlock the admin password.
