Lenovo ThinkPad L421 - Manual (Page 9)

Chapter 1. Overview
AutoLock locks computers automatically by detecting human presence through facial feature recognition.
Locking a computer during user absence can protect confidential data from unintentional exposure. When
the administrator enforces the automatic lock strategy on computers throughout the entire organization, it
will enhance the confidential data security.
AutoLock provides detailed time settings to start camera detection, to show notification before locking, and
to lock the computer. When it is enabled, AutoLock will lock computers at the preset time. Also, AutoLock
enables the administrator to turn its function off temporarily to avoid accidentally locking the computer.
