I keep my computer on all the time, so I don't need that feature. And as I said, I don't quite know how to make it power the computer up. There's also the fact that Dashboard isn't started when the computer powers up, so it'd have to install some furhter startup items to work.

If anyone has any information about how to implement this, I'd be happy to do so, but until then I don't really have any way to do it.
