							FRU Applicable test
TrackPont or Pointing
deviceIf 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 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).
Hard disk drive Fixed Disks (Diagnostics)
CD-ROM drive CD-ROM, DVD, CD-RW, DVD/CD-RW
(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. Power on system and check the air
turbulence at the louver at the rear of
the computer.
2. Run the fan test in Other Devices
(Diagnostics).

							FRU removals and replacements
This section contains information about removals and
replacements.
vDo not damage any parts. Only certified and trained
personnel should service the computer.
vThe arrows in this section show the direction of
movement to remove a FRU, or to turn a screw to
release the FRU. The arrows are marked in numeric
order, in square callout, to show the correct sequence of
removal.
vAny FRUs that must be removed before removing the
failing FRU are listed at the top of the page.
vTo replace a FRU, reverse the removal procedure and
follow any notes that pertain to replacement. See
“Locations”on page 191 for internal cable connections
and arrangement information.
vWhen replacing a FRU, use the correct screw size, as
shown in the procedure.
Safety Notice 1Translations in″Safety Notices (Multi-lingual
Translations)″section: Before the computer is
powered-on after FRU replacement, make sure all
screws, springs, or other small parts are in place
and are not left loose inside the computer. Verify
this by shaking the computer and listening for
rattling sounds. Metallic parts or metal flakes can
cause electrical shorts.
Safety Notice 3Translations in″Safety Notices (Multi-lingual
