I found this problem difficult to search as I kept getting freezing as in stalling not as in temperature. How dangerous is it for laptops, I personally have a macbook pro, to be exposed to cold temperature? I generally take my laptop with me everywhere after class but don't want to carry it with me when I have lunch, or meet with friends etc. In this case I will generally leave my laptop in my car in my backpack. K, backstory done. It is currently -32C here, actually -48C with windchill. As you can imagine it does not take long for a car to cool down and things to freeze. My question is how bad is this for the laptop? I am not leaving it in the car overnight or anything blatently daft like that, but it doesn't take long at these temperatures for things to freeze. I don't just slap the laptop on a desk and fire it up when it feels super cold, just let it slowly aclimatise to room temperature before use. Is this all i should do? Am i still risking my lappy? I really don't want to have to have it attached to me at all times and don't trust leaving it in a coin locker or anything similar.
