Supervisor password
The supervisor password protects the system information stored in the ThinkPad Setup program. If you have
set a supervisor password, no one can change the configuration of the computer without the password. It
provides the following security features:
• If only a supervisor password is set, a password prompt is displayed when you try to start the ThinkPad
Setup program. Unauthorized users cannot access the ThinkPad Setup program without the password.
• The system administrator can use the supervisor password to access 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:
– Changing or deleting the power-on password
– Changing or deleting the supervisor password
– Changing date and time
