Presence sensing
For models with computer vision sensor, your computer supports Presence Sensing feature. This feature offers smarter privacy protection, simpler login experience, and better energy management for your computer.
Note: Before using this feature, ensure you set up Windows Hello facial recognition with the IR camera.
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.
- Lock on leave: Lock the computer automatically when you leave.
- Adaptive Dimming: Track your attention based on head orientation with the display. When you are not facing on your display and not using your keyboard and mouse, the display will dim to save battery power.
