To disable it, press and hold Shift; then press NumLk. Problem: Some or all 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 keyboard do not work. Solution: If you are using the ThinkPad Dock or the ThinkPad Port Replicator, make sure that the keyboard cable is correctly connected to the keyboard connector. If you are using the X3 UltraBase™, you need the keyboard/mouse cable. Make sure that the keyboard/mouse cable is correctly connected to the mouse connector of the X3 UltraBase, and that the keyboard cable is correctly connected to the keyboard connector of the keyboard/mouse cable. 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 cursor drifts when the computer is turned on or after it resumes normal operation.
