i bought my first macbook (13' 2015) and its gets really cold when I'm not using it, like night time. so in the morning its freezing cold. but when i start using it's running normal. its summer here in bc canada so if anything it should be getting hot not cold. i previously had a hp laptop for 3 years and never had this problem. i am worried about the batteries bcoz i know cold temperature shortens battery life is this normal? i was thinking about buying a case or a sleeve. would that solve it? sorry i don't have specific temperatures.
