Supervisor password

The supervisor password protects the system information stored in the ThinkPad Setup. Without it, no one can change the configuration 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 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 Internal Network Option ROM feature

–Changing date and time

–Enabling or disabling the Lock UEFI BIOS Setting feature

–Enabling or disabling the Password at unattended boot

–Specifying the minimum length for power-on passwords and hard disk passwords

–Enabling or disabling the Boot Device List F12 Option

–Enabling or disabling the Boot Order Lock

–Enabling or disabling the Flash BIOS Updating by End-Users feature

–Enabling or disabling the Internal Network device

–Enabling or disabling the Internal Wireless device

–Enabling or disabling the Internal Bluetooth device

–Enabling or disabling the Internal Wireless WAN device

–Enabling or disabling the Security mode

–Enabling or disabling the Reader priority

–Erasing the fingerprint data

Notes:

•The system administrator can set the same supervisor password on many ThinkPad Notebooks to make administration easier.

•By enabling the Lock UEFI Settings in the Password menu when you set the supervisor password, you make it impossible for anyone but you to make changes.
