Let me add my own anecdata: I've been running linux on machines since 1998, and I've never experienced a failure like the one you describe. In fact, the only hardware failures I've experienced have been external (usb) hard drives failing after a few years, and a laptop keyboard failing after someone spilled tea on it. In terms of what the repairman told you, when I called Compaq's support to get help with the keyboard, once the person on the other side of the line heard me say I was running linux on it, he said "that's your problem". I had to reiterate that my problem was someone spilling tea on it, and that I had been running linux on this particular laptop for almost 2 years without any keyboard issues, thank you very much. In the end, Compaq told me they didn't have spare parts, and the keyboard started working again after letting the machine dry up for a few days (that was the last time I bought Compaq though!). My point is: computer repair and tech support people are almost programmed to find out something that they're not responsible for and that could explain your problem. I don't hold it against them, I think it's a normal bias, but I would never take linux advise from a repair person, unless they work on a linux shop.
