Supervisor password
The supervisor password protects the system information stored in ThinkPad Setup. Without it, no one can
change the con guration of the computer. It provides the following security features:
If a supervisor password is set, a password prompt is displayed when you try to start the ThinkPad Setup
program. Unauthorized users cannot get access to con guration data.
The system administrator can use the supervisor password to get access to a computer even if the user of
that computer has set a power-on password. The supervisor password overrides the power-on password.
If both a supervisor password and a power-on password are set, you can do the following only if you
have the supervisor password:
