I am concerned about my Late 08 Macbook 2.0GHz. I am already on my 43rd battery cycle after a month of owning it. I would probably use my Macbook for internet surfing for about a total of 4 hours a day, occasionally listening to music as well. My question is, does it seem like my battery has a fault? I am going to an Apple Store tomorrow and I'm wondering if I should get it checked out whilst I am there. Thanks.
