I recently purchased a new Macbook Unibody 2.4 GHZ. My battery has always been a strange one. The longest it lasts sometimes is only 3 hours and I have only had this for a little more than a month. I just ran coconutBattery it said I have already gone through 37 cycles of battery life? That is weird because I'm pretty sure I've only let it die once..and then recharge it. Ok maybe twice. Another thing I'm speculating is that it sleeps weird. Sometimes when I close the lid it doesn't sleep at all... Although the light is off, the laptop is still hot. Should I take it in the store and get it checked or can I do this myself?
