Windows MCE Sleep Mode
 

I've got a small computer set up with Windows MCE hooked up to my TV for movies and games, but I don't have it on 24/7 like my main computer. So what I like to do is have it go into sleep mode when I press the power button (or use the 'sleep' key on my keyboard). But what I'd like to know is, how can I get it to come out of sleep mode without having to walk over to the computer tower? I'm using a wireless keyboard and mouse, so I keep those on the coffee table by the couch.

Is there some software that would enable this option? My keyboard also has a 'wake up' key but that doesn't seem to do anything, I'm guessing because the computer is not fully powered on? Any suggestions?
