Power-on password

A power-on password protects the system from being powered on by an unauthorized person. The
password must be entered before an operating system can be started. For instructions on how to remove
the power-on password, see "How to remove the power-on password" on page 33.

Hard disk password

There are two kinds of hard disk passwords:
• User hard disk password - for the user
• Master hard disk password - for the system administrator, who can use it to get access to the hard disk
even if the user has changed the user hard disk password
Note: There are two modes for the hard disk password: User only and Master + User. The Master + User
mode requires two hard disk passwords; the system administrator enters both in the same operation. The
system administrator then provides the user hard disk password to the system user.
Attention: If the user hard disk password has been forgotten, check whether a master hard disk password
has been set. If it has, it can be used for access to the hard disk drive. If no master hard disk password is
available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either the
user or the master hard disk password, or to recover data from the hard disk drive. To put the system back
to operational status, the only Lenovo and Lenovo-authorized service solution would be to replace the hard
disk drive or solid-state drive with a scheduled fee.
For how to remove the hard disk password, see "How to remove the hard disk password" on page 34.

Supervisor password

A supervisor password protects the system information stored in the ThinkPad Setup. The user must enter
the supervisor password in order to get access to the ThinkPad Setup and change the system configuration.
Attention: If the supervisor password 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.
