I've had my macbook pro for 3 months now and it says the battery is only 90% of it's max capacity. It says this in the "about this Mac" part and on coconut battery. I usually have the thing connected to the mains ans have gone through 50 charge cycles. I have let it run down to nothing once to see if it would reset the meter thing but no joy. Can you help?
