Macbook Mountain Lion wakes from sleep every 3 minutes..?
I'm on a late 2008 13-inch Macbook running Mountain Lion 10.8.3.
Since installing Mountain Lion, my machine won't stay in sleep mode.
Whether I select 'sleep' from the apple menu or close the lid, it seems to wake every 3 min (I've timed it).
I discovered this when I closed the lid overnight once and found my computer scorching hot in the morning!
I've checked:
- energy saver preferences
- deselected 'wake for network access'
- bluetooth is off
- file sharing is off
Very annoying - please help!
MacBook, OS X Mountain Lion (10.8.3)
