Because the temperature of the laptop in the freezer will always be above dew point it will never get wet. When you take it out though it's temperature will most likely be below dew point of the ambient air so water will condensate unless the access of water is blocked by a plastic bag for example. -- -Matti

Which is why he should turn it off as soon as he takes it out, and let it warm up to room temperature, before he turns it back on.

Which is why he should turn it off as soon as he takes it out, and let it warm up to room temperature, before he turns it back on. And I'd let it sit for a while just to be safe. Turning something on that still has condensation on/in it is a bad thing all the way around. I still remember one time MANY years ago when we got our first color TV. It was cold as heck too. Well, we left it in the back seat of the car while we was running around doing errands and the car never warmed up between trips. We were just bouncing around town. When we finally got home, my Dad brought the TV in and it took a little bit to unhook and move the old TV out and put the new TV in. By that time, it had built up enough condensation somewhere in there that it sparked and a few seconds later it really sparked. Then the smoke got out. We all know what happens when the smoke got out. Brand new TV was junk. If I had put that old thing in the freezer just to play around or something, I'd cut it off before taking it out, take the side off and let it warm up. Once warmed up, put a little fan on it overnight or something to be safe. I might add, my deep freezer runs between -10F and about 0F. I doubt any puter would warm up much unless it is using really small heat sinks. It would certainly be under cooled for a room temp environment. It was just a thought tho. ;-) Dale :-) :-)

;-) Yes, nice. To explain: I only let the thinkpad in there for maybe 10 minutes or so ... So the risk is minimized, I assume. Am 17.
