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.
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 A40 and A40P system board layout on page 67 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.
