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 hard disk password, see "How to remove the hard disk password" on page 42.

Supervisor password

A supervisor password (SVP) protects the system information stored in the ThinkPad Setup. The user must
enter the SVP in order to get access to the ThinkPad Setup 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. Disable the built-in battery. For how to disable the built in battery, see "Disabling the built-in battery"
on page 64.
2. Remove the backup battery. For how to remove the backup battery, see "1070 Backup battery" on
page 79.
3. Connect the ac power adapter and turn on the computer. Wait until the POST ends. After the POST
ends, the password prompt does not appear. The POP has been removed.
4. Disable the built-in battery and reinstall the backup battery.
(B) If an SVP has been set and is known by the service technician:
1. Turn on the computer.
2. When the ThinkPad logo comes up, immediately press F1.
3. Type the supervisor password to enter the ThinkPad Setup program.
4. Select Security, using the cursor directional keys to move down the menu.
5. Select Password.
