System Management Password; How To Remove The Power-On Password - Lenovo ThinkPad X1 Series Hardware Maintenance Manual

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.
Note: When you are prompted by the icon
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.
