Use passwords
This section introduces types of passwords in UEFI (Unified Extensible Firmware Interface) BIOS (Basic
Input/Output System) and how to set, change, and remove a password.
Password types
You can set a power-on password, supervisor password, system management password, or hard disk
password in UEFI BIOS to prevent unauthorized access to your computer. However, you are not prompted to
enter any UEFI BIOS password when your computer resumes from sleep mode.
Power-on password
If you set a power-on password, a window is displayed on the screen when you turn on the computer. Enter
the correct password to use the computer.
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 press Enter to
© Copyright Lenovo 2020, 2021 37
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 43.
Note: When prompted to enter the password, 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.
When prompted to enter a hard disk password, press F1 to switch between the master hard disk password
and user hard disk password.
Note: 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 operating system.

Important battery recycling and WEEE information
Take back and recycling information for WEEE and batteries/accumulators in the European Union and the
United Kingdom
The crossed-out wheeled bin marking applies only to countries with WEEE and batteries waste regulations
including the European Union (EU), and United Kingdom (UK).
Appliances and batteries/accumulators are labeled in accordance with local regulations concerning waste
electrical and electronic equipment (WEEE) and waste batteries and waste accumulators. These regulations
determine the framework for the return and recycling of used appliances and used batteries/accumulators as
applicable within each geography. This label is applied to various products to indicate that the product is not
to be thrown away, but rather put in the established collection systems for reclaiming these end of life
products.
The label on the battery may also include a chemical symbol for the metal concerned in the battery (Pb for
lead, Hg for mercury, and Cd for cadmium).
Users of electrical and electronic equipment (EEE) and users of batteries/accumulators with the crossed-out
wheeled bin marking must not dispose of end of life products as unsorted municipal waste, but use the
collection framework available to them for the return, recycle, and recovery of WEEE and waste batteries/
accumulators and to minimize any potential effects of EEE and batteries on the environment and human
health due to the presence of hazardous substances.
Lenovo electrical and electronic equipment (EEE) may contain parts and components, which at end-of-life
might qualify as hazardous waste.
EEE and waste electrical and electronic equipment (WEEE) can be delivered free of charge to the place of
sale or any distributor that sells electrical and electronic equipment of the same nature and function as the
used EEE or WEEE.
Before placing electrical and electronic equipment (EEE) in the waste collection stream or in waste collection
facilities, the end user of equipment containing batteries and/or accumulators must remove those batteries
and accumulators for separate collection.
