Hi to all!
I had the MBP for 2 months now and overall I'm veeery satisfied with it. Great do-it-all laptop (I mostly use it for software development and gaming).
Anyway, the other day I was in BootCamp while the battery was charging; I didn't pay too much attention to it untill, after some 2+ hours, it was still charging (it had something like 20% left to charge). Rebooted into Mac OS and the battery meter was at 99%; Unplugged the charger and the battery meter went to 100% in battery mode. Plugged again the charger, battery meter back to 99% and battery still went charging (orange light on charger connector).
I reset the <something> (you know, hold Crtl, Command, Alt... and P?), no change.
Took out the battery, pressed and holded the power button for 5 seconds, no change.
I then let the battery drain to 94%, recharged, and eventually it stoped charging.
The point is that now it usually stays a looong time at 99%, altought eventually it stops charging. What surprises me is that when the charger gets unplugged, the meter goes to 100%, CoconutBattery say the battery is fully charged (like 5375 mAh / 5375), but when I plug the charger back, it goes on to charge mode (it shouldn't charge if battery is above 95-96% right?).
Btw, battery has 15 cycle, health is at 96-97%
Is this "normal"? I'm pretty new to Mac OS / MBP but I'm pretty sure it wasn't like this before.
Regards

You need to do a full charge/discharge cycle to reset the meter.

Point is, when everything started I was just calibrating the battery: I had let it discharge and was just recharging it... oh well, I'll try re-calibrating it.
