Problem: All or some of the keys on the external numeric keypad do not work. Solution: Make sure that the external numeric keypad is correctly connected to the computer. Problem: All or some keys on the external PS/2 keyboard do not work. Solution: If you are using the X4 Dock, connect the keyboard connector to the keyboard/mouse connector on the X4 Dock. If you use a mouse and an external keyboard simultaneously, you need the keyboard/mouse connector. Make sure that keyboard/mouse connector is correctly connected to the mouse connector of the X4 Dock, and that the keyboard cable is correctly connected to the keyboard connector of the keyboard/mouse connector. If the connection is correct, disconnect the cable and make sure that the built-in keyboard operates properly. If the built-in keyboard works, there is a problem with the external keyboard. Try using a different external keyboard. TrackPoint problems Problem: The pointer drifts when the computer is turned on or after it resumes normal operation.
