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

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 TrackPo

problem, continue with the following:
