Question

While preparing a computer that will be issued to a new user, the technician discovers the computer's former user configured a supervisor password in the BIOS. Which of the following can the technician do to allow the password to be removed?

Options

  • AReimage the machine from a network share
  • BChange the boot order and boot to an external drive
  • CRemove and then replace the CMOS battery
  • DUse the BIOS user password to reset the supervisor password

Explanation

The BIOS supervisor (administrator) password is stored in CMOS memory, which is a small amount of non-volatile RAM powered by the CMOS battery on the motherboard. Removing the CMOS battery for a minute or two (some boards require longer, or a jumper clear) causes the CMOS to lose power and revert all stored BIOS settings - including the supervisor password - to factory defaults. Reimaging the OS does not affect BIOS settings. Changing the boot order still requires the supervisor password. A BIOS user password cannot override or reset the supervisor password, as the supervisor password has higher privilege.
