-10 is not good for the laptop. Keep an eye on it, I once had someone put a laptop in their trunk overnight in 14F weather, and overnight their LCD became an SCD (Solid Crystal Display)..crunchy, but useless.. check the web sites for ordinary temperatures that you're supposed to use, the thermal stress may not be good for it. (Not to mention they'll give you a hard time and say you invalidated your warranty..:|
I usually tell folks that if they're uncomfortable with the termperature, their PC may be as well. Hope you get to feeling better..
