This program is useful for a computer that is being used as a NAS, it allows the computer to switch to sleep when not required, and when Network card and Media Player (ie Kodi) is configured to WOL, this can save a lot of power.

This program monitors key presses and mouse movements and also checks that the upload speed is not above the threshold (which would indicate streaming).  If none of the events happen in a 10 minute window the program issues a sleep command to Windows

If hibernate is enabled on your computer the computer will hibernate, you can disable hibernate and the computer will only sleep which will not save as much power but videos will start to play faster, run the following command in an elevated command prompt.

powercfg.exe /hibernate off
