Do not discount other hardware problems: video cards, bad capacitors and power supplies. Sadly, I mention these as a subset of my experience. :( I have even had a faulty left mouse button that would lock my X server (many years ago). While holding the button down (scrolling through a menu), the mouse would release and acquire too quickly for the server. Unfortunately, it is harder to find the problem in a laptop where you cannot easily (if at all) switch out pieces of hardware to find the problem. Have you investigated whether or not the laptop is overheating? Sean -- scf@FreeBSD.org
