How cold should a Macbook get?

[stone315]

I'm in college, and I usually go straight from class to practice, which means my Macbook is sitting outside in the lovely New Hampshire weather for a good 2-3 hours, and it's been turning back on at about 18 celsius. How cold is too cold? Like when should I start dropping it off at the dorm instead of bringing it to practice?

Free State!

Anyway, put it in a backpack or nifty AppleSac. Cold is better than hot for computers, so I wouldn't worry too much.

The most harm of cool temp (likewise hot temp) is done to the battery. It can shorten the life time and charge capacity.

10° to 35° C was the operating temp. Aside from the battery, it should be OK if you let the unit warms back up before turning it on.

EDIT: I was wrong. Lithium based batteries like cool storage temp.

Just do NOT bring in your cold macbook from the car into a warm environment and fire it right up. If you can feel moisture building up on the outside of the case - it needs to be powered down until it comes back to temp and dries off. (I would even pull the battery out if I felt it getting moist)

That whole "non-condensing" thing.
