Hi I have owned a black MacBook for a little under a year now and I have always had a "problem" where the battery drains quite fast while it's sleeping. I have owned 2 powerbook's and an ibook and they never used so much battery while sleeping. Before i went to bed the battery level was at 62% and when i woke it up 12 or so hours later is was at 53%. Like i've said, the past apple laptops i've had have not been like this. Does anyone else experience battery drain to this extent?
