Power-on password
A power-on password denies access to the computer by an unauthorized user when
the computer is powered on. When a power-on password is active, the password
prompt appears on the screen each time the computer is powered on. The computer
starts after the proper password is entered.
Removing a power-on password
To service a computer with an active and unknown power-on password, power-off
the computer and use the following procedure.
1. Unplug the power cord and remove the top cover.
2. Refer to “Identifying parts on the system board” on page 28 to find the recovery
jumper.
3. Move the recovery jumper from normal to clear .
4. Power-on the computer. The system senses the change in the position and erases
the password.
It is necessary to move the jumper back to the previous position.
5. Remind the user to enter a new password when service is complete.
Note: On some models, this procedure will also remove the administrator password.
