Passwords
As many as three passwords might be needed for any 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 appears on the screen whenever the computer is
turned on. The computer does not start until the password is entered.
Note: If only the supervisor password is set, the password prompt does not appear when the operating
system is booted.
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 booted. For how to remove the power-on
password, see “How to remove the power-on password” on page 34.
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 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 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
