Some laptops have an integrated numberpad with the keys mapped to a 4x4 area on the keyboard. To use the number pad for games, you need to toggle the keyboard mode by pressing SHIFT-NUMLOCK or whatever. It's usable but not convenient because you have to keep switching back to the regular mode when you need to type any of the letters that it uses.
