Passwords
As many as three passwords might be needed for a ThinkPad notebook computer: the power-on password,
the hard disk password, and the supervisor password.
If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the
computer is turned on. The computer does not start until the password is entered.
Note: If only a supervisor password is set, the password prompt will not be displayed when the operating
system is started.
Power-on password
A power-on password protects the system from being turned on by an unauthorized person. The password
must be entered before the 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 36.
Hard disk password
There are two 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 User . The 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 a master hard disk password has been set, it can be used to access 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 hard disk password 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.
