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.
