I saw the question Will cold weather break my laptop?...
I have a similar question, but it's different.
One of the answers there posted a list of top-10 recommendations for what to do. (source: About.com) It seemed to sound authoritative, except on closer examination some of the things were inconsistent, and all of them were pretty vague ("let it warm up") and lacked supporting science. For example:
Never leave a laptop, even in a well-padded and insulated laptop case in the trunk of vehicle in cold weather. The laptop could freeze and you lose all data contained in it.
I was not aware that simple cold temps could cause a hard drive to fail. Also, how cold is cold? What does it mean to "freeze" a laptop? What's the freezing point of laptops?
Q1: Is there any basis for the claim that "freezing" a laptop could cause loss of data?
One of the other recommendations is to "let it warm up."
Q2: Is this reasonable?
I read elsewhere that warming up a laptop can cause condensation, and THAT, and not simply cold temperature, is the potentially damaging factor. In this case it might be better to turn on the laptop and let it warm itself up.
Can someone help me out with an authoritative answer, rather than one based on opinion or "this always worked for me"?
