I did a search but didn't see anything related to Hot Corners. '11 MBP sleeps fine and light blinks when I close the lid and also when I go to the Apple then Sleep. When I use a Hot Corner, it appears to be asleep, but the light does not pulsate. The same happens when I go to Energy Settings and adjust it to sleep automatically...no blinking. Brand new Mac. No apps open, nothing installed other than pages and numbers. Any advice?
