To start off with, i am new to mac and i am a windows convert. The new MacBook is awesome, however i noticed some strange glitches here and there, one of them being the battery indicator. Here's some of the things that occur : 1- The battery indicator does not show that the macbook is charging, unless you restart or go to sleep/wake up the MacBook. It makes a noise, once the power cable is plugged in, but it does not show that its charing. Only shows as if the laptop is still running off battery. 2-The battery indicator shows that theres lets say 40 % batter, and then it suddenly jumps down to 20 -30%. All these errors can be easily fixed with a restart or a sleep/wake up of the MacBook. What i want to know, is it just a software issue? Or could it be hardware related ?
