Supervisor and hard disk passwords:
The
supervisor password (PAP) and the hard disk password
(HDP) are security features that are used to protect the
system and the hard disk data from unauthorized access.
No overriding capability is provided. If only a hard disk
password is set, you must get the password from its owner
in order to run diagnostic tests and perform service. If
both the supervisor password and the hard disk password
are set, you can enter Easy-Setup by pressing the Enter
key or by entering the power-on password at the
supervisor password prompt. In this case, the Password,
Start up, Network, and Initialize or Asset ID (for some
models) icons cannot be selected.
Note: The supervisor password and the hard disk
password cannot be replaced if they are forgotten.
If the customer forgets the supervisor password,
the system board must be replaced. If the
customer forgets the hard disk password, the hard
disk drive must be replaced.
How to remove the power-on passwords:
If only the power-on password is set, do the following to
remove it:
1. Turn off the computer.
2. Remove the DIMM cover from the bottom of the
computer.
3. Short-circuit the two password pads or put the jumper
on the pins.
For the location of the password pads or the jumper,
see “Password pads” on page 68.
4. Turn on the computer and wait until the POST ends.
After the POST ends, the password prompt does not
appear. The power-on password has been removed.
5. Reinstall the DIMM cover.
If both the power-on password and the supervisor
password are set, do the following to remove them:
1. Power on the computer by pressing and holding F1.
2. Enter the supervisor password. The Easy-Setup
menu appears.
3. Click the Password icon.
4. Click the Power on icon.
5. Enter the supervisor password, and press the Space
bar.
6. Press Enter twice.
7. Click Exit; then click Restart.
The power-on password has been removed.
