Hey i'm new to macs. I've had my MacBook Pro for about 6 months now and love it. There has been an annoying buzzing sometimes when i move screen, but thats a different matter. This is about my battery. Its health is only at 65% is this normal for a 6 month old Macbook Pro? Any help would be great! Thanks.

Something wrong there... Apple says:
A properly maintained Apple notebook battery is designed to retain up to 80% of its original capacity after 300 full charge and discharge cycles.

You've got nearly twice the degredation with only half the cycles.

137 cycles in 6 mos (3 cycles every 4 days) seems a bit high... what's your usage profile like?
