Hey, I have noticed that, with my C2D Macbook Pro, the sleep light stays on if the lid is down and an external monitor is connected - even though the machine is running. If I open the lid (while running w/ the external monitor) the light goes off; then if I shut it the light comes back on again. Not a big deal but somewhat annoying. Anyone have any ideas? I don't particularly want to take it back (at least yet) for a non-performance-related issue.
