It depends on who you ask:
IBM/Lenovo: Track Point
HP/Compaq: PointStick
NEC: NX Point
Sony: Pointing Stick
Fujitsu: StickPoint, QuickPoint
Dell: Track Stick
Toshiba: Accupoint
Acer: Finetrack
Anyway, when you sa y"Came off", do you mean: "the rubber/foam sleeve popped off", or do you mean "the enture pointer assembly snapped off"?
The sleeve itself is normally replacable, and should be dirt cheap. However, if the entire thing snapped off then you'll most likely need to replace the keyboard itself (the pointer thing is part of the keyboard, and not a seperate component)
either way it's not terribly difficult, but replacing the keyboard is obiously more complicated since on most systems it involves taking the laptop casing apart to get access to it.
