FRU Applicable test

TrackPont or

Pointing device

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

pointer drifts on the screen for a short

time. This self-acting pointer move-

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

necessary if the pointer movement

stops in a short period of time.

If this does not correct the TrackPoint

problem, continue with the following:
