I have a Mac Mini from late 2006 with an intel Core duo cpu (Model#: MA608LL/A). The problem I'm having is that i have it set to turn the display off after idling 5min and go to sleep after idling for 10min. It turns the display off but the mac never goes to sleep. I can use the apple remote or the menu option to put it to sleep. It just never goes to sleep due to idling. Any possible solutions would be great.
