Hey guys I am on OS X 10.8.2 currently and have been experiencing GIANT battery issues (despite the fact that everyone says it is better). Up until today it was fully charging (100%) but would drain 3-4% a min... then today I got home from work and opened up my computer (plugged in) and it says 0% charge and to replace the battery. So is there a good chance this is beta software issues and if so is there anyway to reset or test it? Or is it truly a hardware issue? And if that is the case how much am I looking to get a MBP battery replaced?
