Supervisor password

The supervisor password protects the system information stored in UEFI BIOS. When entering the UEFI

BIOS menu, enter the correct supervisor password when you are prompted by the icon

. You also can

press Enter to skip the password prompt. However, you cannot change most of the system configuration

options in UEFI BIOS.

If you have set both the supervisor password and power-on password, you can use the supervisor password

to access your computer when you turn it on. The supervisor password overrides the power-on password.

System management password

The system management password can also protect the system information stored in UEFI BIOS like a

supervisor password, but it has lower authority by default. The system management password can be set

through the UEFI BIOS menu or through Windows Management Instrumentation (WMI) with the Lenovo

client-management interface.

You can enable the system management password to have the same authority as the supervisor password

to control security related features. To customize the authority of the system management password through

the UEFI BIOS menu:

1. Enter the UEFI BIOS menu. See “Enter the UEFI BIOS menu” on page 47.

Note: When you are prompted by the icon

, enter the correct supervisor password if a supervisor

password has been set, or enter the correct system management password if no supervisor password

has been set. Otherwise, you cannot change the configurations in the following steps.

2. Select Security ➙ Password ➙ System Management Password Access Control.

3. Follow the on-screen instructions.

If you have set both the supervisor password and the system management password, the supervisor

password overrides the system management password. If you have set both the system management

password and the power-on password, the system management password overrides the power-on

password.

Hard disk passwords

The hard disk password prevents unauthorized access to the data on the storage drive. When a hard disk

password is set, you are prompted to type a correct password each time you try to access the storage drive.

To set the hard disk password, select one of the following types:

• User hard disk password only

When a user hard disk password is set without a master hard disk password, the user must enter the user

hard disk password to access files and applications on the storage drive.

• Master hard disk password + User hard disk password

The master hard disk password is set and used by a system administrator. It enables the administrator to

access any storage drive in a system or any computer connected in the same network. The administrator

can also assign a user hard disk password for each computer in the network. The user of the computer

can change the user hard disk password as desired, but only the administrator can remove the user hard

disk password.
