Just got a new 2010 macbook and the weird thing is that every time I put the notebook to sleep it seems to go into deep sleep within an hour or so. Lately it went after a few minutes of being closed. All the times that it's doing this it was put to sleep with full battery and still had most left when opened back up. My last macbook didn't do this, and would only revert to deep sleep when it was almost out of battery? Do I need to get this checked out? Is any one else experiencing this? Any help would be greatly appreciated.
