Hello, I have a MacBook Pro Mid 2012 13" with the i5. I have always had this sleep and wake problem since I upgraded to Mountain Lion. Basically, if my MacBook Pro is asleep with the lid open and I close it, the MacBook Pro will wake up. There are no blutooth devices connected and I have already tried restoring operating system and setting up as new. I would like to mention Lion 10.7 did not have this issue. It only happens with Mountain Lion. Does anyone else have this problem?? When I went back to Lion, the problem went away. Apple Genius can't figure it out neither could AppleCare.
