        No, it wasn't.  Just some very basic (and kinda ugly) LED's in the
corner that don't tell/show a whole lot.  Just the typical lights for AC
Power, Battery charging/dying, Suspend, Caps Lock, Scroll Lock, and Num Lock
(and oh yeah--Hard Drive light).  Nothing especially informative beyond the
very basics.
