Solving computer problems
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.
Solution: The cursor might drift when you are not using the TrackPoint
during normal operation. This is a normal characteristic of the TrackPoint and
is not a defect. Cursor drifting might occur for several seconds under the
following conditions:
v When the computer is turned on.
v When the computer resumes normal operation.
v When the TrackPoint is pressed for a long time.
v When the temperature changes.
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.
Make sure that the mouse or pointing-device cable is securely connected to
the computer.
