Supervisor password
The supervisor password protects the system information stored in the 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 appears when you try to start the ThinkPad Setup.
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:
Deleting the power-on password
Changing or deleting the supervisor password
Enabling or disabling the Wake on LANand Flash over LAN features
Enabling or disabling the Internal Network Option ROM feature
