UltraNav 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 the pointing device does not work.
Solution: Make sure that the TrackPoint and the touch pad are set to
Automatic in the ThinkPad Configuration Program. Then detach the mouse or
the pointing device, and try using the TrackPoint and the touch pad. If the
TrackPoint and the touch pad work, the error might be due to the mouse or
the pointing device.
Make sure that the cable for the mouse or the pointing device is securely
connected to the docking station or the port replicator.
Note: For more information, see the manual supplied with the mouse.
