I have my brightness around 3 notches and I started charging it when it displayed the warning thing. It was calculating how long it took to charge it and istat pro says 616:25? After it was done calculating, it said it took about 2 hours. I have been charging for an hour now and the battery is only charged only at 30%. My power brick is really weird too. It used to be hot and warm all over but right now it is warm in some spots and cold in some. Should I worry about this?
