Solving computer problems Solution: v Make sure that the keyboard cable is correctly connected to the computer. v If you are using the keyboard/mouse cable, make sure that the cable is correctly connected to the computer, and that the keyboard cable is connected to the correct side of the keyboard/mouse cable. v If you are using the docking station or the port replicator, make sure that the keyboard cable is correctly connected to the keyboard connector. If these connections are correct, disconnect the external keyboard from the computer and make sure that the built-in keyboard operates properly.

Problem: The cursor does not work for a while after the settings in the Mouse Properties window have been changed. Solution: This is a normal characteristic of the cursor. Wait several seconds until the cursor returns to the normal state. Problem: The mouse or pointing device does not work. Solution: Make sure that the TrackPoint is enabled in the ThinkPad Configuration Program, and then try using the TrackPoint. If the TrackPoint works, the error might be due to the mouse.
