My MacBook Pro has been waking up from sleep at some of the most random times. Usually it will wake up about 5 minutes after I put it to sleep, and if I'm lucky it will stay to sleep when I try again. Sometimes it will even wake up 30 or 45 minutes after I put it to sleep. Currently, I have it connected to an external display with the laptop screen closed at all times. It is running a fresh install of Snow Leopard with barely any apps installed yet (mainly just iWork and Microsoft Offiice). I was having the same problem when I was running Leopard, thats why I did a fresh install. So this eliminates a software issue. This has been happening for a few months now, but it has just started to become a problem for me. When I was running Leopard I did not have an external display. It was waking up at random times without anything connected to it (no display, USB, or MagSafe connected). I would be sitting next to my Mac, and all of a sudden, I hear the Superdrive wake up sound. I searched and found a thread similar to this, but hopefully it will not have the same solution as the members of the following thread had: "I had this problem with my Macbook. The fix was a logic board replacement." http://forums.macrumors.com/showthread.php?t=557953 I have also attached a screenshot of my system.log in Console. I opened up console as soon as my MBP woke by itself. Hopefully someone here will have some idea what all the stuff in console means or maybe be able to narrow down the problem. Thanks so much!
