v Power-on Password
v Administrator Password
v Operating System Password
Power-on and Administrator passwords are set in the Setup Utility program.
See “Setup Utility program” on page 122 for information about running the
Setup Utility.
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 “A20 system board layout (Type 6269)” on page 146 or
“A40/A40P system board layout
(Types 6058/6059/6578/6579)” on page 148 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.
Administrator password: The administrator password is used to restrict
access to the Configuration/Setup Utility program. If the administrator
password is activated, and you do not enter the administrator password, the
configuration can be viewed but not changed.
