Your computer supports the Presence Sensing feature with the ToF sensor. This feature offers smarter privacy protection, simpler login experience, and better energy management for your computer.
Note: Before using this feature, ensure that the ToF sensor is not
covered by any object such as a tape.
This feature provides the following functions:
- Wake on approach: Wake your computer from sleep mode when you approach it and face on your display. With Windows Hello facial recognition, you can log in without touching your computer.
