Note: You are responsible for evaluating, selecting, and implementing the locking device. Lenovo makes no
comments, judgments, or warranties about the function, quality, or performance of the locking device and

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, 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
