Supervisor password
The supervisor password protects the system information stored in ThinkPad Setup. No one can change the
computer configuration without the supervisor password. 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 configuration 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 LAN feature
