If the TrackPoint does not work, see if
an external PS/2 mouse is connected
to the mouse/keyboard connector and
remove it. The TrackPoint is automat-
ically 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

ment can occur when a slight, steady
pressure is applied to the TrackPoint
pointer. This symptom is not a hard-
ware problem. No service actions are
