I have a MacBook Air and I have noticed that even though I have configured it to put itself into sleep mode after being inactive for 5 minutes it sometimes stays awake.
I've usually got a bunch of programs open (Tweetie, iTunes, Safari, iChat etc) but it there some way I can find out which program/process that is preventing the MacBook from sleeping? (Yes, I know that I could probably reboot the MacBook and try one program at a time but that is pretty tedious)
can a CPU-hogging browser prevent the MacBook from sleeping? – jimr – 2010-12-19T22:30:05.203
I have seen flash-ads on the current page of the current browser cause a system to refuse to sleep-and-stay-asleep. – benc – 2010-12-22T05:52:38.270
