Supervisor password<br />
The supervisor password protects the system information stored in the ThinkPad Setup. Without it, no one<br />
can change the configuration of the computer. It provides the following security features:<br />
• If a supervisor password is set, a password prompt appears when you try to start the ThinkPad Setup.<br />
Unauthorized users cannot get access to configuration data.<br />
• The system administrator can use the supervisor password to get access to a computer even if the user of<br />
that computer has set a power-on password. The supervisor password overrides the power-on password.<br />
• If both a supervisor password and a power-on password are set, you can do the following only if you<br />
have the supervisor password:<br />
– Deleting the power-on password<br />
– Changing or deleting the supervisor password<br />
– Enabling or disabling the Wake on LANand Flash over LAN features<br />
– Enabling or disabling the Internal Network Option ROM feature<br />
