The laptop I had before the last was an Asus Eeepc that developed a dodgy AC adaptor port. I still have it and it could be made to work, but it was never a very good computer in the first place. It runs loud and hot for what it is. Before that, and the oldest computer I still have in my closet, is my T60p thinkpad. I'd need to buy a replacement fan before using that one again, and I'm not sure it would be worth the hassle to resurrect (again.) If I were inclined to fix up an old thinkpad I think I'd rather get a second-hand X-series since they're not nearly so huge.
