I get this problem both in Linux and Windows, so I won't rule out hardware/bios bugs, but I find that often when my monitor (backlight) gets turned off automatically after a long period of non-use, the computer freezes up. I think it only happens when I've left it that way for a long time, though. If I move the mouse immediately after the screen is blacked, I have no trouble, but if I leave it for a long time, when I get back the monitor won't unblack, ctrl-alt-backspace does nothing, ctrl-alt-delete does nothing, Fn-Suspend, Fn-A don't do anything, and the capslock and numlock keys don't do anything either. I haven't tried reaching the machine from outside yet, but I will if someone wants. Possibly useful note: when the computer is in this state and I remove the (PCMCIA) network card and re-insert it, it does not get reset. This could indicate a complete lockup.
