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:
Mouse (Interactive Tests).
Hard disk drive
Fixed Disks (Diagnostics)
Diskette drive
1. Diskette Drive (Diagnostics)
2. Diskette (Interactive Tests)
CD-ROM or
DVD-ROM drive
CD-ROM/DVD (Interactive Tests)
Memory
1. If a DIMM is installed, remove it
and run Memory Test-Quick
(Diagnostics)
2. If the problem does not recur,
replace the DIMM and run the
test again.
3. If the test does not detect the
error, run Memory Test-Full
(Diagnostics)
Fan
1. Start Windows 98 and check the
air turbulence at the louver at the
rear of the computer.
2. Run the fan test in Other Devices
(Diagnostics).
