Read This First
Before you go to the checkout guide, be sure to read this
section.
Important Notes
Only certified trained personnel should
service the computer.
Read FRU Removal and Replacement
procedures before replacing any FRUs.
Be extremely careful during write operations
such as copying, saving, or formatting.
Drives in the computer that you are servicing
might have been rearranged or the drive start-up
sequence might have been altered. If you select
an incorrect drive, data or programs might be
overwritten.
Replace FRUs only for the correct model.
When you replace a FRU, make sure the model
of the machine and FRU part number are correct
by referring to the FRU parts list.
A FRU should not be replaced because of a
single, unreproducible failure. Single failures
can occur from a variety of reasons that have
nothing to do with a hardware problem, such as:
cosmic radiation, electrostatic discharge, or
software errors. FRU replacement should be
considered only when a recurring problem exists.
If this is suspected, clear the error log and run
the test again. Do not replace any FRUs if log
errors do not reappear.
Be careful not to replace a nondefective FRU.

Screw Tightening Information
Loose screws can cause a reliability problem. The IBM
ThinkPad computer addresses this problem with
nylon-coated screws. Tighten screws as follows:
Plastic to plastic
Turn an additional 90 degrees after the screw head
touches the surface of the plastic part:
Logic card to plastic
Turn an additional 180 degrees after the screw head
touches the surface of the logic card:
Torque driver
If you have a torque driver, refer to the “Torque”
instruction with each step.
How to Use Error Messages: Use the error
codes displayed on the screen to diagnose failures. If
more than one error code is displayed, begin the diagnosis
with the first error code. Whatever caused the first error
code can result in false error codes being displayed. If no
error code is displayed, see if the error symptom is listed
in the “Symptom-to-FRU Index” on page 23.
Port Replicator Problems: If you suspect a
problem with the port replicator, see “Port Replicator
Checkout” on page 18.
How to Diagnose Multiple FRUs: When the
adapter or the device has more than one FRU, the error
code could be caused by any of them. Before replacing
multiple FRUs, try removing or exchanging each FRU, one
by one in the designated sequence, to see if the symptoms
change.

5. Failure symptoms, error codes appearing on the
display, and beep symptoms
6. Procedure index and page number in which the

7. Failing FRU name and the part number
8. Machine type, model number, and serial number
9. Customer's name and address
Before checking problems with the computer, determine
whether the damage is covered under the warranty by
