TrackPoint or
pointing device
If the TrackPoint does not work, check the
configuration in the ThinkPad Configuration
program. If the TrackPoint is disabled, select
Enable to enable it.
After you use the TrackPoint, the pointer
may drift on the screen for a short time. This
drift can occur when a slight, steady
pressure is applied to the TrackPoint pointer.
This symptom is not a hardware problem.
No service action is necessary if the pointer
stops after a short time
If enabling the TrackPoint does not correct
the problem, continue with the following.
