Supervisor password
The supervisor password protects the system information stored in UEFI BIOS. When entering the UEFI
BIOS menu, enter the correct supervisor password in the window prompted. You also can tap 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 asupervisor 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 throughthe UEFI BIOS menu:
1. Enter the UEFI BIOS menu. See “Enter the UEFI BIOS menu” on page 31.
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.
• 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 toaccess 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 computercan change the user hard disk password as desired, but only the administrator can remove the user harddisk password.
When prompted to enter a hard disk password, follow the on-screen instructions to switch between themaster hard disk password and user hard disk password.
Notes: The hard disk password is not available in the following situations:• A Trusted Computing Group (TCG) Opal-compliant storage drive and a TCG Opal management software
program are installed in the computer, and the TCG Opal management software program is activated.
• An eDrive storage drive is installed in the computer preinstalled with the Windows 10 operating system.

Set, change, and remove a password

Customer Replaceable Units (CRUs) are parts that can be upgraded or replaced by the customer. The
computers contain the following types of CRUs:• Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or bytrained service technicians at an additional cost.
• Optional-service CRUs: Refer to parts that can be installed or replaced by customers with a greater skill
level. Trained service technicians can also provide service to install or replace the parts under the type of
warranty designated for the customer’s machine.
If you intend on installing a CRU, Lenovo will ship the CRU to you. CRU information and replacement
instructions are shipped with your product and are available from Lenovo at any time upon request. Youmight be required to return the defective part that is replaced by the CRU. When return is required: (1) return
