Should I take my MacBook Pro in for service? I have almost 180 charge cycles on my battery. My computer is a June '09 revision 2.53GHz 13" I've been calibrating my battery, and my life seems to be diminishing. Yesterday, it said I had a full charge capacity of 7800 mAH! (I think that's about 2000 more than the battery can handle) Today, I took this screenshot, and as you can see the capacity has drastically dropped. I've calibrated it about 5 times this week, and the range STILL varies every day! iStat Pro reads 74% health. What should I do? I still get about 4 hours of life, and whenever i calibrate it, the unit drops down to 0% really quickly, then runs for about 45 minutes. After that, it reads 2%, and runs for another 3.5 hours. I'm really quite perplexed as to what is happening, I'm thinking it might even be my logic board... Thank you for your help!
