TrackPoint or
pointing device
If the TrackPoint does not work, check the
configuration as specified in the ThinkPad
Configuration program. If the TrackPoint is
disabled, select Automatic 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

is not a hardware problem. If the pointer stops
after a short time, no service action is
necessary.
If enabling the TrackPoint does not correct the
problem, continue with the following:
