Got the new 27" i7 iMac a month ago and I converted over from PC, so I'm new to Macs.
When I leave my Mac left on it goes to sleep after 15 minutes, but when I come back a few hours later, I can't wake it up with the keyboard or mouse.
The screen is black, but the system is still warm, so I believe it is still on.
Pressing the power button does nothing.
The only thing I can do is a force restart with Control-Command-Power button.
Does anyone know what is causing this and how I can fix it so it can wake up with the keyboard or mouse?
