TrackPont or Pointing	If the TrackPoint does not work, see if an
device	external PS/2 mouse is connected to the
	mouse/keyboard connector and 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:
	Mouse (Interactive Tests).

	turbulence at the louver at the rear of
	the computer.
