Hello to some of my favorite forum goers, Alaska is very cold. With my last laptop (white MacBook) I would often leave my backpack (laptop inside, sleeping) in my car while I was at work, because sometimes I have to go straight from school to work and I'd rather it was locked securely in my vehicle than sitting around in my building. It ranges from about -15˚F to 35˚F here in the winter. Apple operating temperature range: 50˚F-95˚F Storage (off, not sleeping, I would assume) temperature range: -13˚F-113˚F Does anyone have personal experience or somewhat definitive proof/advice of whether this may cause damage to my system? I suppose shutting it down beforehand might be a good idea. I'm mainly worried about opening it up and using it directly afterwords, in a room temperature building. I never experienced any abnormalities while using my white MacBook this way. Thanks in advance!
