I'm using an old laptop that one of the clan put together for about $25. Just love being cheap that way. I guess I take after Billy. Funny I have an uncle named Billy and he's just as cheap. But back to the trick. This little laptop has been running quite a bit and started to hang up so I stuck it in a plastic bag and put it in the freezer overnight. Took it out and let it warm up for an hour. Poped it back in and everything seems fine so far. We'll see how long it lasts. You can't say I didn't get my money out of this thing.
Update: It looks like that is only a temporary fix in order to recover your data. After about an hour it was back to it's unfixed old self (hanging up and not loading pages. None the less it is still a neat trick if you keep important stuff on your computer. Back up you say. I don't need no stinking back up!
