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 and BBC iPlayer amongst others. If Sleep# does not manage to detect the end of the video with a particular application, it will send the computer to sleep when the screensaver becomes active at the end of the video.

    I made an account just to review this software. Its bug FREE, it works flawlessly and now I can finally have my HTPC shut itself off at night. Thank you so much!

    Appears to work very well on my Windows 7 setup. I like to have some background music playing before sleep, suing Windows Media Player. Have only used the Countdown Timer feature so far, but will experiment with the others. Could perhaps do with some more detailed instructions.

    klitos: By default, the minimum full screen time of a full screen video (VLC or Windows Media Player) is 5 minutes for Sleep# to kick in. The system also needs to be idle for at least 3 minutes. These values can only be changed by editing the configuration file, but I don't think you will need to. Please let me know if it works with a longer video.

    Very nice program! Is there a way to customize the countdown timer? Would like this option because I need an option between 10 and 30 min. @chrisshields: Thank you! Would be very useful.
