Before you go to the checkout guide, be sure to read this
section.
Important Notes
Only certified trained personnel should
service the computer.
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 startup sequence
might have been altered. If you select an
incorrect drive, data or programs can be written
over.
Replace FRUs only for the correct model.
When you replace the FRU, make sure the
model of the machine and FRU part number are
correct by referring to the part list.
FRUs 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 defect; such as:
cosmic radiation, electrostatic discharge, or
software errors. FRU replacement should be
considered only when a recurring problem exists.
If you suspect an unreproducible failure, clear the
error log and run the test again. Do not replace
any FRUs if log errors do not reappear.
Do not replace a nondefective FRU.
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. The cause of 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 18.
How to Diagnose Multiple FRUs: When the
adapter or device has more than one FRU, the error code
could be caused by either FRU. Before replacing multiple
FRUs, try removing or exchanging each FRU, one by one
in the designated sequence, to see if the symptoms
change.
What to Do First: The servicer must include the
following in the FRU exchange form or FRU return form
that is attached to the returned FRU.
1. Name and phone number of servicer
2. Date of service
3. Date when FRU failed
4. Date of purchase
1
5. Failure symptoms, error codes appearing on
display, and beep symptoms
6. Procedure index and page number in which
failing FRU was detected
7. Failing FRU name and FRU number
8. Machine type, model number, and serial number
9. Customer's name and address
Before checking problems with the computer, refer to the
following to determine if the warranty applies.
Warranty Note
During the warranty period, the customer may be
responsible for repair costs if the computer damage
was caused by misuse, accident, modification,
unsuitable physical or operating environment, or
improper maintenance by the customer.
The following is not covered under warranty:
LCD panel cracked by applying excessive force
or by being dropped.
Scratches, cracked, or broken plastic parts,
broken latches, broken pins, or broken
connectors caused by excessive force.

PCMCIA card or installation of an incompatible
card.
Damage caused by foreign material in the
UltraBay or half-height bay.
Diskette drive damage caused by pressing the
diskette drive cover or inserting diskettes with
multiple labels.
Damaged or bent diskette eject button.
CD-ROM drive damage caused by excessive
force, shock, or by being dropped.
Fuses blown by attaching a nonsupported device.
Forgotten computer or hard disk password
(making computer or hard disk unusable).
If the following symptoms are present, they may
indicate damage caused by nonwarranted activity:
Missing parts may be a symptom of unauthorized
service or modification.
HDD spindles can become noisy if subjected to
excessive force or by being dropped.
I9990303 errors can be caused by exposure to
strong magnetic fields.

Model and SelectaDock when docked together as one
unit.
1. The SelectaDock supports the ThinkPad 760E,
760ED, and 760ELD. When any other model is
docked to the SelectaDock, a beep sounds. Check
which model of the ThinkPad is docked to the
SelectaDock before maintenance.
2. Verify the Base Model is correctly docked (connected)
to the SelectaDock.
3. Verify the computer is correctly docked (connected) to
the SelectaDock Docking System.
4. Dock a known-good computer to the Base Model and
verify proper operation. If there is a problem, replace
the Base Model.
5. If possible, make sure there are no hardware setting
conflicts, such as in interrupt levels, memory
addresses, DMA channels, and I/O addresses.
6. If the PCI or the ISA card is installed, verify the card
is supported by the computer.
7. Verify the SCSI ID is set correctly.
8. Test and correct any computer problems before you

Checkout Guide
Use the following procedure as a guide for computer
problems.
Note
The diagnostic tests are intended to test only IBM
products. Non-IBM products, prototype cards, or
modified options can give false errors and invalid
system responses.
Important
When the problem determination procedure in the
operation manual that is supplied with the adapter or
device says “Have the system unit serviced”, this
means both the computer and the SelectaDock
Docking System.
1. Obtain the failing symptoms in as much detail as
possible.
2. Verify the symptoms by attempting to re-create the
failure by running the diagnostic test or by repeating
the same operation.
Note
To run the diagnostics, refer to “How to Run the
Diagnostics” on page 11.
3. Use the following table with the verified symptom to
determine which page to go to. Search the
symptoms column and find the description that best
matches your symptom; then go to the page shown in
the “Go to” column.

Power Supply
If the power-on indicator is not on but the power supply fan
is not turning, check the power cord for continuity and
correct installation.
If the power cord is not the problem, either the power
supply is defective, or another component is defective
causing the power supply to cut off. To verify the power
supply is operating correctly, do the following:
1. Power-off the computer and disconnect the
SelectaDock Docking System power cord.
2. Remove all internal devices, external devices, and the
computer from the SelectaDock Docking System.
3. Undock the Base Model.
4. Remove the half-height bay frame (see “1050
Half-Height Bay Frame” on page 39).

Checking the Installed Devices List
If a device is installed but the icon appears in a gray shade
rather than a dark shade on the basic diagnostics screen,
the device is defective. Reseat the device connectors. If
the symptom remains, replace the device or the system
board. If needed, adjust the contrast control to clearly
distinguish the shades of the icon.
If a device that is not installed appears in a dark shade (for
example, FDD-2 appears in a dark shade when
second FDD is installed), do the following:
1. Replace the first device in the configuration, such as
an FDD-1, HDD-1.
2. If the problem remains, replace the system board.
The PCMCIA-1, parallel, and serial icons are always
displayed in a dark shade because the icons represent
subsystems of the system board and not the attachment of
the devices.
The FDD-1, HDD-1, or PCMCIA-1 icons represent the first
drive in the system configuration for each type of device.
Similarly, the HDD-3, FDD-2, or PCMCIA-2 icons represent
the second drive, usually attached through a port
replicator or an expansion unit.
The HDD-2 icon represents the hard disk drive in the
UltraBay of the computer. The HDD-3 or HDD-4 icons
represent the hard disk drive in the SelectaDock Docking
NO

System (except the SCSI hard disk). The FDD-2 or
PCMCIA-2 icons represent the FDD or PCMCIA attached
through a port replicator or in the SelectaDock Docking
System.
Printer
Test the printer by connecting it to the computer before
testing it on the SelectaDock Docking System.
1. Make sure the printer is correctly connected and is
powered on.
2. Run the printer self-test.
If the printer self-test does not run correctly, the problem is
in the printer. Refer to the printer service manual.
If the printer self-test runs correctly, connect a wrap plug
on the parallel connector on the rear of SelectaDock
Docking System and run the advanced diagnostic tests to
determine the failing FRU.
If the advanced diagnostic tests (with the wrap plug
connected) did not detect a failure, replace the printer
cable.
If the problem is not corrected, do one of the following:
If the printer is attached to the parallel connector of
SelectaDock Docking System, replace the main card
of SelectaDock Docking System.
If the printer is attached to the parallel connector on
the adapter, replace the FRUs in the following order
one at a time until the problem is corrected:
