If the TrackPoint does not work, see if an
external PS/2 mouse is connected to the
mouse/keyboard connector. If so, remove
it. The TrackPoint is automatically
disabled if an external PS/2 mouse is
attached. Check also if the TrackPoint
driver is correctly installed by accessing
Windows Device Manager via the System
icon in the Control Panel.
After you use the TrackPoint, the pointer
drifts on the screen for a short time. This
self-acting pointer movement can occur
when a slight, steady pressure is applied
to the TrackPoint pointer. This symptom
is not a hardware problem. No service
actions are necessary if the pointer
movement stops in a short period of time.
If this does not correct the TrackPoint
problem, continue with the following:

1. Start Windows and check the air
turbulence at the louver at the rear of
