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 do the
following:
Note
On some models, this procedure will also remove the
administrator password.
1. Unplug the power cord and remove the top cover.
2. Refer to “System board layout” on page 77 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.
