My new Mac Mini goes to sleep but when I wake it (move mouse or press space bar) the mini starts spinning awake but the LCD monitor (new as well) with the Mac adapter goes to sleep. How can I correct this? I have a new Windows Mac compatible USB keyboard with a new Gigaware Mac compatible USB mouse. I've had to hard-power the machine down several times to shut down. None of the hot key shut down/quit commands have any effect. What is the deal? Thanks!
