What's keeping my Windows computer awake?
Just discovered a way to find what's keeping my Windows computer awake or my screen from going black.
- Open up an elevated command prompt.
- 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!
