title: Preventing Sleep on Surface Pro
body: <p>I want to create an application that can run in the background, with the screen off, but prevent the Surface Pro from sleeping.  Essentially, I have an audio book player, but as soon as I turn off the screen to listen to the audio book and attempt to save power, the Surface goes to sleep.  In fact, the only way I know how to prevent sleep is to keep the display on, but I explicitly don't want to do that as I want to save power.  Because of this, the <a href="http://msdn.microsoft.com/en-us/library/windows/apps/br241816.aspx" rel="nofollow">DisplayRequest class</a> is not a good solution for this problem.</p>
