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 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 ngerprint 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.
Setting a supervisor password
Only a system administrator will be able to apply this procedure.
