Note: After restoring a drive to the factory default settings, you might need to reinstall some device drivers.

Passwords

As many as three passwords may be needed for any ThinkPad Notebook: the power-on password (POP),
the hard-disk password (HDP), and the supervisor password (SVP).
If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is
turned on. The computer does not start until the password is entered.
Note: If only an SVP is installed, the password prompt does not appear when the operating system is booted.

Power-on password

A power-on password (POP) protects the system from being powered on by an unauthorized person. The
password must be entered before an operating system can be booted. For how to remove the POP, see
"How to remove the power-on password" on page 41.

Hard-disk password

There are two hard-disk passwords (HDPs):
• User HDP—for the user
• Master HDP—for the system administrator, who can use it to get access to the hard disk even if the user
has changed the user HDP
Note: There are two modes for the HDP: User only and Master + User. The Master + User mode requires
two HDPs; the system administrator enters both in the same operation. The system administrator then
provides the user HDP to the system user.
Attention: If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be
used for access to the hard disk drive. If no master HDP is available, neither Lenovo nor Lenovo authorized
service technicians provide any services to reset either the user or the master HDP, or to recover data from
the hard disk drive. The hard disk drive can be replaced for a scheduled fee.
For how to remove the POP, see "How to remove the hard-disk password" on page 42.

Supervisor password

A supervisor password (SVP) protects the system information stored in the BIOS Setup Utility. The user must
enter the SVP in order to get access to the BIOS Setup Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the service technician, 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 no SVP has been set:
1. Turn off the computer.
2. Remove the battery pack. For how to remove the battery pack, see "1010 Battery pack" on page 68.
3. Remove the backup battery. For how to remove the backup battery, see "1100 Backup battery" on
page 82.
