TrackPoint or
pointing device
If the TrackPoint does not work, check
the configuration in the ThinkPad Config-
uration program. If the TrackPoint is disa-
bled, 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 enable the TrackPoint does not correct
the problem, continue with the following.
