all problems with warning battery service appeared after an upgrade. everything get stacked and i used Onyx to be cool again. I have a macbook pro(8,2) early 2011 with 10.8.5 and battery health was 88% (430 battery loads - 30 months macbook). After the upgrade (2 weeks now or a month i cant remember) i have 60% of battery health and 436 battery loads. I tested recalibration for the battery (without leaving my pc sleeping for 5 hours) and of course i opened from behind to get out the battery and making the trick with the 30sec... but nothing happened except than when i reconnect power cord fans started....Dan any advise about this?i need a step by step guide doing the work rightly..and then i will go to an AASP...or not? haha
cheers
