Explanation
The cursor is moving because Joe's palms or wrists are accidentally brushing the touchpad while typing - a very common laptop issue. Using an Fn key combination (e.g., Fn+F7 on many laptops) to disable the built-in touchpad costs nothing and directly eliminates the cause. An external keyboard or mouse would require purchasing additional hardware, raising the cost. Locking the keypad (Fn+NumLk) disables the numeric keypad overlay, not the touchpad, and does not address the problem.
