What’s keeping my Windows computer awake

Just discovered a very simple way to find what’s keeping my Windows computer awake or my screen from going black.

  1. Open up an elevated command prompt.
  2. Run the following command
    > powercfg -requests

While playing a video in Windows Media Player I get this output:

DISPLAY:
[PROCESS] \Device\HarddiskVolume2\Program Files (x86)\Windows Media Player\wmplayer.exe

SYSTEM:
[DRIVER] High Definition Audio Device (HDAUDIO\FUNC_01&VEN_10EC&DEV_0888&SUBSYS_1458A102&REV_1000\4&1454c4ac&0&0001)
An audio stream is currently in use.
[PROCESS] \Device\HarddiskVolume2\Program Files (x86)\Windows Media Player\wmplayer.exe

AWAYMODE:
None.

EXECUTION:
None.

PERFBOOST:
None.

Simple and clear!

    I got this without running any program. Does anyone know what this is?
    thanks for the help

    • Svchost is a general binary which hosts background services. So… One of your services is keeping your computer awake. You might be able to figure out which one through the task manager or the resource monitor 😊
