Depends on where that winter is. Here in Phoenix, snow makes news (and whatever you do, don't ask Phoenicians to drive in it, they're bad enough in rain!) and with the exception of outlying areas, there's now seldom even frost in the morning. -10C or so? YIKES! So using a laptop outside in winter here isn't likely to trigger the behavior in question. OTOH, I've personally had the opposite issue, go away for some hours in the summer with the computer left running, AC fails when it's already 45C in the shade outside, come back to a house baking at 55-60C inside, a computer still on but of course crashed, and head-crashed disk that likely reached well over 70C... Still, once I shut down and cooled everything down, the system but for the disk was fine, and the disk was fine too, outside the zones where the heads happened to be at the time. I had (unmounted at the time) backup partitions on the same disk that I was able to boot and run from for several months, until I was able to buy and install a replacement. -- Duncan - List replies preferred.
