Sleep#: Save Power. No More Noise!
Send computer to sleep after VLC, WMP, Google Play Movies & TV
*** For the latest v5 with integrated YouTube Web (controllable with the YouTube app on your phone) please download from https://www.microsoft.com/en-gb/p/sleep/9ppgrg6t7dcj *** Do you use your computer for playback of films, streamed TV etc. before going to sleep? In these cases, Windows' sleep functionality is suspended and won't kick in once the video has finished. The solution for many is to use a sleep timer to send the computer to sleep after the estimated amount of time of the video. But you need to remember to do this every time. Sleep# handles this automatically: Sleep# sends your computer to sleep after the playback of fullscreen video, providing Windows has been idle for a predefined amount of time. There is a grace period at the end of the fullscreen video before sending your computer to sleep, allowing you to interrupt the process should you still be awake. Sleep# works with VLC media player, Windows Media Player, Google Play Movies & TV amongst others. -

There are even a few tabs if you want to seperate them a little bit. * Requires .NET 4.5 Note : If you dont see the icon in your tray, just drag it next to your clock.
