TrackPoint or
pointing deviceIf the TrackPoint does not work, check the
configuration in the ThinkPad Configuration
program. If the TrackPoint is disabled, select
Automaticto enable it.
After you use the TrackPoint, the pointer may
drift 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. If the pointer stops
after a short time, no service action is
necessary.
If enabling the TrackPoint does not correct the
problem, continue with the following:

							Fn key combinations
The following table shows the function of each combination
of Fn with a function key.
Key
combinationDescription
Fn+F1 Reserved.
Fn+F2 Reserved.
Fn+F3 Turn off the LCD display, leaving the screen
blank. To turn the LCD display on again, press
any key or the TrackPoint stick.
Fn+F4 Put the computer in standby mode. To return to
normal operation, press the Fn key
independently, without pressing a function key.

							Symptom-to-FRU index
The symptom-to-FRU index in this section 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 column headed“FRU or
action, in sequence.”If replacing a FRU 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 likely to need to be replaced
next.
A numeric error is displayed for each error detected in
POST or system operation. In the displays,ncan be any
number.
If no numeric code is displayed, check the narrative
descriptions of symptoms. If the symptom is not described
there, go to“Intermittent problems”on page 56.
NoteFor an IBM device not supported by diagnostic
codes in the ThinkPad notebook computers, see the
manual for that device.

							LCD-related symptoms
ImportantThe 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:
vXGA:8 or more bright dots, 8 or more dark dots,
or a total of 9 or more bright and dark dots.
vSXGA+:11 or more bright dots, 13 or more dark
dots, or a total of 16 or more bright and dark
dots.
Note:A bright dot means a pixel is always on
(white or color.) A dark dot means a pixel is
always off (black color.)
Symptom or error FRU or action, in sequence
No beep, power-on indicator
on, and a blank LCD during
POST.System board.

							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 problem recurs.
When analyzing an intermittent problem, do the following:
1. Run the diagnostic test for the system board in loop
modeat least 10 times.
2. If no error is detected, donotreplace 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, wrong devices are installed,
a short circuit is suspected, or the system is inoperative.
Follow these procedures to isolate the failing FRU (do not
isolate FRUs that have no defects).
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 38.)
1. Power off the computer.
2. Visually check each FRU for damage. Replace any
damaged FRU.
3. Remove or disconnect all of the following devices:
a. Non-IBM devices
b. Devices attached to the port replicator
c. Printer, mouse, and other external devices
d. Battery pack
e. Hard-disk drive
f. External diskette drive
g. DIMM
h. CD-ROM and diskette drive in the Ultrabay
i. PC Cards
4. Power on the computer.
5. Determine whether the problem has changed.
6. If the problem does not recur, reconnect the removed
devices one at a time until you find the failing FRU.
7. If the problem remains, replace the following FRUs one
at a time (do not replace a nondefective FRU):
a. System board
b. LCD assembly
