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

002

Have the computer serviced.

003

– Install the computer on Dock II. Make sure that the

computer is firmly connected.

– Check all cables and power cords.

– Check the fan in the power supply in Dock II and make

sure it is working correctly.

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.

– Reinstall all external devices.

– Turn on all external devices.

The problem was not detected by the diagnostics.

Check that the cables and connectors are not

damaged.

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.

396 IBM Mobile Systems HMM - Volume 1

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.
