Some Windows 11 PCs have a presence sensor built in. If your PC has one, you can have your screen turn off automatically when you leave, and then have your device wake up quickly when you approach. This can help keep your PC more secure, help save battery power, and help you get back to work more quickly. 

To determine if your PC has a presence sensor, check to see if it has the Presence settings mentioned below. If it does, you can turn it on or off and change settings for it anytime—you’re in control. For more info, see the Microsoft Privacy Statement

To change your presence settings 

  1. Select the Start button, then enter settings. Select Settings > System > Power & battery.

  2. On the Power & battery screen, select Screen and sleep.

  3. Turn on one or both of the following: 

    • To have your screen turn off when you leave, turn on Automatically turn off my screen when I leave.

    • To have your device wake when you approach it, turn on Automatically wake up my device when I approach.

  4. To change the Presence settings, select More options (>) next to Automatically turn off my screen when I leave or Automatically wake up my device when I approach.

  5. In Presence settings, you can then change these settings:

    • Consider me gone when I’m this far away. The distance that determines when you have left your PC.

    • Then, turn off my screen after this amount of time. How long to wait before your screen turns off after you have left your PC.

    • Wake my device when I’m this close. Determines how close you need to be for your PC to wake when you approach it.

      Note: Some devices might have more than one presence sensor. If so, you can choose which one you want to use.
