Hi, a few days ago i notice that my macbook seems to loose some battery in a few hours when i put it to sleep (close the lid). Like it is 100% at 3:00 AM and when im going to use it at 12 or so, the battery is like 50% or so, i seems weird to me cause this thing use to have an awesome battery! Today i use my MB and at 5:00PM i went to work (i just close the lid and put it on my backpack) now at 7:00PM (2 hours later) I was looking for my camera on my backpack and the MB was HOT as hell!, i took it out and i was still ON! What is happening!? Could having my MB turn on on my backpack a few times (i dont know how many times this has happen) damage something on my MB!!??
