Attention
If the user HDP is forgotten, check to see if a
master HDP was set. If a master HDP was set and
can be recalled, this will allow access to the
hard-disk drive. If no master HDP is available, IBM
does not provide any services to reset either the
user or the master HDP nor recover data from the
hard-disk drive. The hard-disk drive can be replaced
for a scheduled fee.
Supervisor password:
A supervisor password (SVP) protects the system
information stored in the IBM BIOS Setup Utility. The SVP
must be entered in order to access the IBM BIOS Setup
Utility and make changes to system configuration settings.
Attention
If the SVP has been forgotten and cannot be made
available to the servicer, there is no service
procedure to reset the password. The system board
must be replaced for a scheduled fee.
How to remove the power-on password
To remove a POP that you have forgotten, do the
following:
(A) If SVP is not installed:
1. Turn off the computer.
2. Remove the battery pack.
For how to remove the battery pack, see “1010 Battery
pack” on page 57.
3. Remove the backup battery.
For how to remove the backup battery, see “1020
Backup battery” on page 58.
4. Turn on the computer and wait until the POST ends.
After the POST ends, the password prompt does not
appear. The POP has been removed.
5. Reinstall the backup battery and the battery pack.
(B) If SVP is installed and known by the servicer:
1. Turn on the computer by pressing and holding F1.
2. Enter the SVP. The IBM BIOS Setup Utility menu
appears.

the menu.
