TrackPoint
or

deviceIf the TrackPoint does not work, check
the configuration in the ThinkPad
Configuration program. If the
TrackPoint is disabled, select Enable
to enable it.
After you use the TrackPoint, the
pointer drifts on the screen for a short
time. This drift can occur when a
slight, steady pressure is applied to the
TrackPoint pointer. This symptom is
not a hardware problem. No service
action necessary if the pointer stops
after a short time.
If this does not correct the TrackPoint
problem, continue with the following.

Fn key combinations
The following table shows the function of each combination
of Fn with a function key.
The Fn key works independently from the operating
system. The operating system obtains the status through
the system management interface to control the system.

							Symptom-to-FRU index
  Symptom-to-FRU index
The symptom-to-FRU index lists symptoms and errors and
their possible causes. The most likely cause is listed first,
in boldface type.
 Note 
Do the FRU replacement or other actions in the
sequence shown in the “FRU/Action in Sequence”
column. If a FRU replacement does not solve the
problem, put the original part back in the computer.
Do not replace a nondefective FRU.
This index can also help you determine, during regular
servicing, what FRUs are liking to need to be replaced
next.
A numeric error is displayed for each error detected in
POST or system operation. In the displays, n can be any
number.
If no numeric code is presented, check the narrative
description of symptoms. If the symptom is not described
there, go to “Intermittent problems” on page 46.
 Note 
For IBM devices not supported by diagnostic codes in
the ThinkPad notebook computers, see the manual for
that device.

LCD-related symptoms
 Important 
The TFT LCD for the notebook computer contains
many thin-film transistors (TFTs). A small number of
dots that are missing, discolored, or always lighted is
characteristic of TFT LCD technology, but excessive
pixel problems can cause viewing concerns. The LCD
should be replaced if the number of missing,
discolored, or lighted dots in any background is:

SVGA (12.1 in.):5 or more bright dots, 5 or
more dark dots or a total of 9 or more bright and
dark dots.

XGA (13.3 in.):8 or more bright dots, 8 or more
dark dots or a total of 9 or more bright and dark
dots.

Intermittent problems
Intermittent system hang problems can be due to a variety
of causes that have nothing to do with a hardware defect,
such as: cosmic radiation, electrostatic discharge, or
software errors. FRU replacement should be considered
only when a recurring problem exists.
When analyzing an intermittent problem, do the following:
1. Run the diagnostic test for the system board in loop
mode at least 10 times.
2. If no error is detected, do not replace any FRUs.
3. If any error is detected, replace the FRU shown by
the FRU code. Rerun the test to verify that no more
errors exist.
  Undetermined problems
You are here because the diagnostic tests did not identify
which adapter or device failed, installed devices are
incorrect, a short circuit is suspected, or the system is
inoperative. Follow these procedures to isolate the failing
FRU (do not isolate nondefective FRUs).
Verify that all attached devices are supported by the
computer.
Verify that the power supply being used at the time of the
failure is operating correctly. (See “Power system
checkout” on page 29.)
1. Power off the computer.
2. Visually check each FRU for damage. Replace any
damaged FRU.
