The IBM* ThinkPad* Dock II (hereinafter referred to as the
Dock II
) expands the capability of the IBM ThinkPad 360,
750, and 755 notebooks (hereinafter referred to as the
computer
), using the IBM AT* Bus architecture.
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.
Warning
Drives in the computer that you are servicing
might have been rearranged or the drive startup
sequence might have been altered. Be
extremely careful during write operations such as
copying, saving, or formatting. Data or programs
can be written over if you select an incorrect
drive.
Only certified and trained personnel should
service the computer.
The parts exchange form or parts return form
attached to the FRU to be returned must
describe the following:
– Name and phone number of servicer (in
print).
– Date serviced.
– Date failed.
– Date purchased.
– Failure symptoms, error codes, and beep
symptoms.
– Procedure index and page number on which
the symptom or error code is described.
– The failing FRU name and part number.
– Machine type, model number, and serial
number.
– Customer name and address
Checkout Guide: 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 list provides some common items that are
not covered under warranty and some symptoms that may
indicate the system was subjected to stresses beyond
normal use.
390 IBM Mobile Systems HMM - Volume 1
The following are not covered under warranty:
LCD panel cracked by applying excessive force or
being dropped
Scratched (cosmetic) parts
Cracked or broken plastic parts, latches, or
connectors caused by excessive force
Damage caused by liquid spilled into the system
Damage caused by improperly inserting a PCMCIA
card or installation of a incompatible card
Damage due to foreign material in the FDD or FDD
bay
If the following symptoms are present, they may
indicate damage caused by non-warranted activity:
Missing parts may be a symptom of unauthorized
service or modification.
HDD spindles become noisy if subjected to high
levels of force or being dropped
I9990303 errors may be caused by exposure to
extreme magnetic fields
Overall Procedure
1. Check that the computer is correctly docked
to Dock II.
2. If possible, make sure that there are no hardware
setting conflicts, such as in interrupt levels, memory
addresses, DMA channels, and I/O addresses.
3. Check that the SCSI ID is set correctly.
4. Test and correct any computer problem before you
test it with Dock II. Use the computer documentation
to resolve any computer problems.
5. Test the computer with the external keyboard,
external display, mouse, and parallel and serial
device connectors. (Use the keyboard/mouse
connector to test the external keyboard and mouse.)
If no problems are found, connect the external
keyboard, mouse, parallel and serial devices to Dock
II, then connect Dock II to the computer and test it.
6. If external devices are attached to Dock II, such as an
audio amplifier, check the device by referring to the
manual shipped with the device.
7. If the user did not bring the computer with
Dock II when service is needed, use a computer that
works correctly with Dock II.
How to Diagnose Combined FRUs: If an
adapter or device consists of more than one FRU, an error
code can be caused by any of the FRUs. Before replacing
the adapter or device, remove the FRUs, one by one, to
see if the symptom changes.
Dock II (3546) 391
(CONTINUED)
How to Use Error Messages: The error
messages caused by Dock II, the attached computer, and
the attached devices are displayed on the LCD of the
attached computer or on the external display. 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 the error code is displayed, see the “Symptom-to-FRU
Index” on page 416.
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
the computer and Dock II.
001
– Turn off the computer and all external devices.
– Remove the computer from Dock II.
– Connect the external keyboard, mouse, parallel and
serial devices to the computer, if used. (Use the
keyboard/mouse connector for testing the external
keyboard and mouse.)
– Diagnose all computer problems first (see the computer
Hardware Maintenance Service
manual).
DID THE TEST COMPLETE WITHOUT ANY ERROR?
Yes No

Notes:
1. The mouse or some other pointing device do not
work if they are connected to the keyboard/numeric
keypad connector.
2. The mouse or some other pointing device do not
work if they are connected to the mouse connector
on the numeric keypad that is connected
to Dock II.
3. The computer keyboard does not work when an
external keyboard is connected to Dock II.

If a SCSI device is not installed, start at Step 3.
If a SCSI device is installed, do the following:
1. Check that the total number of the attached
SCSI devices is less than eight.
2. Check that the SCSI terminator is correctly
installed.
If the problems still remain, run the SCSI test.
(See “Running Diagnostics” on page 410.)
3. Reconnect all adapters, drives, and devices,
then test the system several times. A Loop
Test option is available for running all the tests.
(See “How to Run the Loop Test” on
page 407.)
After stopping the loop test, check that the error
log appears in the error list. (See “Error Log”
on page 409.)
If no errors were detected, go to “Undetermined
Problems” on page 421 and use the user
reported symptom.
If any errors are detected, go to “Numeric Error
Codes” on page 418.
021
Note the error code and go to “FRU Codes” on page 419
and replace the appropriate FRUs. If the problem remains
after all repair actions are taken, go to “Undetermined
Problems” on page 421.

Checking the Installed Devices
The HDD-1 or FDD-1 represents the first drive in the
system configuration, respectively. Similarly, the HDD-2 or
FDD-2 represents the second drive, usually attached
through a Dock II.
Notes:
1. Neither the Dock II nor the adapters and SCSI
devices installed in the Dock II appear as icons on
the screen.
2. HDD-1 and HDD-2 icons are for the 2.5-inch
ThinkPad hard disk drive.
If the devices are installed, but the icon appears in a gray
shade rather than a dark shade on the basic diagnostic
screen, it means that the devices are defective. Turn off
the computer and make sure that the devices are correctly
connected. If the symptom still remains after the computer
is turned on, replace the devices or the main card of Dock
II.
Dock II (3546) 397
Power Supply
If the power-on indicator is not on and 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 that the
power supply is operating correctly, do the following:
1. Turn off the computer and disconnect the Dock II
power cord.
2. Remove all internal and external devices, and the
computer from the Dock II.
3. Remove the power supply connector CN26 from the
main card (refer to “Main Card” on page 453) and
CN56 from the riser card (refer to “Riser Card” on
page 455).
4. Remove the SCSI power supply connector from the
SCSI device.
5. Install jumpers between pins 1 and 2, and pins 3 and
4 of JP2 on the main card.
6. Connect the Dock II power cord.
7. Check the power supply voltages on the CN26,
CN56, and SCSI connectors by referring to the
respective voltage tables. Then, check that the fan is
turning. If the voltage is not correct or the fan is not
turning, replace the power supply.
8. Connect the Dock II power cord.
If any of the voltages are not correct, replace the power
supply. If replacing the power supply does not correct the
problem, then replace the main card.
