The Lenovo BIOS Linux WMI interface provides the following benefits:

• Flexible BIOS configuration, including the ability to change a single BIOS setting or all BIOS settings

• BIOS password management, including updating supervisor passwords and power-on passwords

Supported computers

BIOS setup through ThinkLMI is supported on all Lenovo Linux certified platforms from 2020 onwards. Whilst

we expect it to work on older platforms it is unsupported there.

Typical Usage

Using ThinkLMI, the BIOS settings can be configured in the following ways:

• List BIOS settings

• Change BIOS settings

• Change the boot order (sometimes referred to as the startup sequence)

• Change BIOS Password(Supervisor password and power-on password)

Listing Available BIOS Settings

For a list of all available BIOS settings that can be changed through Linux WMI on a specific computer, use

the following command.

ls /sys/class/firmware-attributes/thinklmi/attributes

The above command retrieves all the settings available from the BIOS. Part of the output from ThinkPad Z16
