Sleep (ie screen off and bottom left light blinking was working fine until yesterday.
Then I noticed that only the display wnet to sleep - the bottom left light stayed on steady but the display shut off.
In that mode I could wake the display by pushing any key on the keyboard or moving the mouse - just like the Mac.
But now it seems the display also won't go to sleep.
I checked energy saving settings on the Mini and also the bios settings, those are fine.
I did install iLife '08 and iMovie '06 and iWorks - wonder if any of those cause the problem.
