FRU Replacement

Strategy

 

 

 

 

 

 

 

 

Before

Replacing

Parts

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ensure that all diskette fixes are installed prior to

replacing

any

 

FRUs

listed

in

this

manual.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Use the following strategy to prevent unnecessary FRU replacement and service expense:

Ÿ

If you

are instructed

to replace a FRU

and

that

 

does

not

correct the

problem,

reinstall

the

original

 

FRU

before

you

continue

.

 

 

 

Ÿ

Some

computers

have both a processor board and a

 

system board. If you are

instructed to replace either

 

the

processor

board

or the system board, and the first

 

board that you replaced does not correct the problem,

 

reinstall the original board, then replace the other

 

(processor

or

system)

board.

 

Ÿ If

an

adapter or device consists of more

than

one

FRU,

an error code may be caused by any

of

the

FRUs. Before replacing the adapter or device,

 

remove

the FRUs, one by one, to see if the

 

symptoms change. Replace only the FRU that

 

 

changed

the symptoms.

 

 

 

Attention

 

 

 

 

 

 

 

 

 

 

 

A customized setup configuration (other

than default

settings)

may

exist on the computer you

are servicing.

Running Automatic Configuration may alter those

settings. Note

the

current configuration

settings (using

the View Configuration option) and verify that the

settings

are

in place when service is complete.

The

advanced diagnostic tests are intendedonly

to test

IBM

products. Non-IBM products or modified options can

give

false errors and invalid responses.

 

Hard

Disk Drive

Replacement Strategy:

Always try

to

run a

low-level

format before replacing a hard

disk

drive.

 

 

 

 

 

 

 

Attention

 

 

 

 

 

 

 

 

 

 

 

 

 

The drive startup sequence in the computer you are

servicing might have been changed. Be extremely

careful during write operations such as copying,

saving, or formatting. Data or programs can be

overwritten

 

if you

select

an incorrect drive.

 

 

 

 

 

 

 

 

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 for the

computer

you

are

servicing.

How

to

Read

POST

Error

Messages

POST

error messages

are displayed on the screen as

three,

four,

five, or

eight digits. The error messages that

can

be

displayed

as

shorter POST messages are

highlighted in this index. Some digits will represent different information for SCSI errors versus non-SCSI errors.

The following example shows which digits display the shorter POST error messages and also defines the SCSI information in an eight-digit error message.

Shorter POST Messages *3333-3333-3333-33330

Slot

Number (SCSI)

 

 

Device Code

+

Logical Unit Number (SCSI)

 

 

 

 

ID (SCSI)

 

 

All SCSI devices are set to a different SCSI ID.

Duplicate SCSI ID settings can generate

a false

error

message. Use the SCSI ID to determine

whether

the error

message is coming from an internal or an

external

device.

Safety Notice 7

Though main batteries have low voltage, a shorted or grounded battery can produce enough current to burn combustible materials or personnel.

Bien que

le voltage des batteries principales soit peu

élevé, le court-circuit ou la mise à la masse d'une

batterie peut produire suffisamment de courant pour

brûler des matériaux combustibles ou causer des

brûlures

corporelles

graves.

 

Obwohl Hauptbatterien eine niedrige Spannung

haben,

können sie doch bei Kurzschluß

oder Erdung

genug Strom abgeben, um brennbare Materialien zu

entzünden oder Verletzungen bei Personen

hervorzurufen.

 

 

Sebbene le batterie di alimentazione siano a basso

voltaggio,

una batteria in corto circuito o a massa può

fornire corrente sufficiente da bruciare materiali

combustibili o provocare ustioni ai tecnici di

manutenzione.

 

 

Aunque

las

baterías

principales tienen

un voltaje bajo,

una batería cortocircuitada o con contacto a tierra

puede producir la corriente suficiente como para

quemar

material combustible o provocar quemaduras

en el

personal.

after

maintenance.

 

 

Ÿ When

lifting

any

 

heavy

object:

 

 

 

 

1.

Ensure

you

can

stand

safely

without

slipping.

2.

Distribute the weight of the object equally

between

your

feet.

 

 

 

 

 

 

3.

Use

a

slow lifting force. Never move suddenly

or

twist

when you attempt to lift.

 

 

4.

Lift

by

standing or by pushing up with your leg

muscles; this action removes the strain from the

muscles in your backDo .not attempt to lift any

 

objects

that

weigh

more than

16

kg

(35 lb)

or

objects

that

you think

are too

heavy for

you.

ŸDo not perform any action that causes hazards to the

customer, or that makes the equipment unsafe.

ŸBefore you start the machine, ensure that other

service

representatives

and the

customer's

personnel

are

not

in a

hazardous

position.

 

Ÿ Place

removed

covers and

other

parts in a

safe

 

place, away from all personnel, while you are

 

 

servicing

the

machine.

 

 

 

 

 

 

 

Ÿ Keep

your tool case away

from walk areas so that

 

 

other

 

people

will

not

trip

over it.

 

 

 

 

Ÿ

Do

not

wear

 

loose

clothing

that can be trapped in the

 

moving

parts

of

a

machine. Ensure

that

your

sleeves

 

 

are fastened or rolled up

above

your

elbows. If

your

 

hair

is

long,

fasten

it.

 

 

 

 

 

 

Ÿ

Insert

the

ends

of

your

necktie

or

scarf

inside

clothing

 

or fasten it with a nonconductive clip, approximately 8

 

centimeters

(3

inches) from

the

end.

 

 

 

 

Ÿ

Do

not

wear

 

jewelry,

chains, metal-frame

eyeglasses,

 

or metal fasteners for your clothing.

Attention: Metal objects are good electrical conductors.

ŸWear safety glasses when you are: hammering,

drilling soldering, cutting wire, attaching springs, using

solvents, or working

in

any other conditions that might

be hazardous to

your

eyes.

ŸAfter service, reinstall all safety shields, guards,

labels, and ground wires. Replace any safety device that is worn or defective.

ŸReinstall all covers correctly before returning the machine to the customer.

Introduction15

Electrical Safety

Observe the following rules when working on electrical equipment.

 

Important

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Use

only

approved tools and test equipment. Some

hand

tools

 

have

handles

covered

with a

 

soft material

that does not insulate you when working with live

electrical

currents.

 

 

 

 

Many customers have, near their

equipment, rubber

floor mats that contain small conductive fibers to

decrease electrostatic discharges. Do not use this

type

of

mat to

protect

yourself from

electrical shock.

 

 

 

 

 

 

 

 

 

 

ŸFind the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the

 

switch

or

unplug

the

power

cord

quickly.

 

 

Ÿ

Do

not

work

alone under hazardous conditions or

 

near equipment

that

has

hazardous

voltages.

 

Ÿ

Disconnect

all power

before:

 

 

 

 

 

Performing

a

mechanical inspection

 

 

 

 

Working

near

power

supplies

 

 

 

 

 

Removing

or

installing

main

units

 

 

 

 

Ÿ

Before

you

start

to

work

on the machine, unplug the

 

power

cord.

If

you

cannot

unplug it, ask the customer

 

to

power-off

the

wall

box

that

supplies

power

to the

 

machine

and

 

to

lock

the

wall box

in

the

off

position.

ŸIf you need to work on a machineexposedthat has

electrical circuits, observe the following precautions:

Ensure that another person, familiar with the power-off controls, is near you.

Attention: Another person must be there to switch off the power, if necessary.

Use only one hand when working with

 

powered-on electrical equipment; keep

the

other

 

hand in your pocket or behind your back.

 

 

Attention:

There

must

be

a

complete

circuit

to

 

cause electrical shock. By observing the above

 

rule, you may prevent a current from passing

 

through your

body.

 

 

 

 

 

 

 

 

When

using

testers,

set

the

controls

correctly

 

and use the approved probe leads and

 

 

 

accessories

for

that

tester.

 

 

 

 

Stand

on

suitable

rubber

mats

(obtained

locally,

 

if necessary)

to

insulate

you from

 

grounds

such

 

as metal floor strips and machine frames.

 

 

Observe

the

special

safety

precautions

when

you

work

with

very

 

high

voltages;

these instructions

are in

the safety sections of maintenance information. Use

extreme

care

when

measuring

high

voltages.

Ÿ

Regularly inspect and maintain your

electrical

hand

 

tools

for safe

operational

condition.

 

Ÿ

Do not

use

worn

or

broken

tools and testers.

 

Ÿ

Never

assume that

power has

been

disconnected

 

 

from a circuit.checkFirst,that it has been

 

 

powered-off.

 

 

 

 

 

Ÿ

Always

look

carefully

for possible

hazards in

your

 

work area. Examples of these hazards are moist

 

floors, nongrounded power extension cables, power

 

surges, and

missing

safety

grounds.

 

ŸDo not touch live electrical circuits with the reflective

surface of a plastic dental mirror. The surface is

conductive;

such touching can cause personal injury

and

machine

damage.

Ÿ Do

not

and similar units. (This practice ensures correct

grounding

of

the

units.)

 

Ÿ If

an

 

electrical

accident

occurs:

Use

caution;

do not

become

a victim

 

yourself.

 

 

 

 

 

Switch

Safety Inspection Guide

The intent of this inspection guide is to assist you in

identifying potentially

unsafe conditions

on these

products.

Each machine, as it was designed and built,

had

required

safety items installed

to protect users

and

service

personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM

features

or

options not

covered by this inspection guide.

If

any

unsafe

conditions

are present, you must determine

how

serious

the

apparent

hazard could be and whether

you

can

continue

without

first correcting the problem.

Consider these conditions and the safety hazards they present:

ŸElectrical hazards, especially primary power (primary

voltage on the frame can cause serious or fatal electrical shock).

Ÿ Explosive hazards, such as a damaged CRT face or bulging capacitor

ŸMechanical hazards, such as loose or missing hardware

Introduction17

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1.

Check

exterior

covers

for

continuity for 0.1 ohm or less between the

 

 

external

ground

 

pin

and

frame

 

ground.

 

 

 

b. The

power

cord

should

be the

appropriate type

 

 

as

 

specified

in the

parts

listings.

 

 

 

c.

Insulation must

 

not

be

frayed

or

worn.

 

 

4.

Remove

the

cover.

 

 

 

 

 

 

 

 

 

 

5.

Check

18 IBM Mobile Systems - ThinkPad HMM Volume 3

Handling Electrostatic Discharge-Sensitive Devices

Any computer part containing transistors or integrated

circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD

damage by equalizing the charge so

that

the

machine, the

part,

the

work

mat,

and

the

person

handling

the

part are all

at the same

charge.

 

 

 

 

 

 

 

 

Notes

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. Use

product-specific ESD procedures

when they

 

 

exceed

the requirements

noted

here.

 

 

 

2.

Make

sure

that

the

ESD

protective

devices

you

 

 

use have been certified (ISO 9000)

as fully

 

 

effective.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

When handling ESD-sensitive parts:

ŸKeep the parts in protective packages until they are

 

inserted

into

the

product.

Ÿ

Avoid contact

with

other

people.

Ÿ

Wear a grounded wrist strap against your skin to

 

eliminate

static on

your

body.

ŸPrevent the part from touching your clothing. Most

 

clothing

is

insulative

and

retains a charge even when

 

you

are

wearing

a

wrist

strap.

 

 

 

 

 

 

Ÿ Use

the

black

side

of

a

grounded

work

mat

to provide

 

a static-free work surface. The mat is especially

 

useful

when

handling

ESD-sensitive

devices.

 

 

Ÿ Select a grounding system,

 

such

as

those

listed

 

below, to provide protection that meets the specific

 

service

requirement.

 

 

 

 

 

 

 

 

 

 

 

 

Note

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The

use

 

of

a

grounding

system

is

 

desirable

but

 

not

required

to

protect

against

ESD

 

damage.

 

 

 

 

 

 

– Attach the ESD ground

clip to any frame ground,

 

 

ground

braid,

or

green-wire

ground.

 

 

 

– Use

 

an

ESD

common

ground

or reference

point

 

 

when working on a double-insulated or

 

 

 

 

battery-operated system. You can use coax or

 

 

connector-outside

shells

 

on these

systems.

 

Use the round ground-prong of the AC plug on AC-operated computers.

Grounding Requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.

What to Do First

Before servicing the computer, determine whether or not the damage applies to the warranty by referring to the following:

 

 

Warranty Note

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

During the warranty period, the customer

may be

responsible

for repair costs if the 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

could indicate that the system was subjected to stresses

beyond normal

use.

 

 

Warranty

Coverage

Notes

 

 

 

 

 

The following

is

not

covered under warranty

:

ŸLCD panel cracked from being dropped or

applying too much force.

ŸScratched (cosmetic) parts.

ŸCracked or broken plastic parts, broken latches,

 

broken pins or connectors caused by excessive

 

force.

 

 

 

 

 

 

 

 

 

 

 

Ÿ

Damage

caused

by

liquid

spilled

onto

the

system.

Ÿ

Damage

caused

by

improperly

inserting

a

 

 

PCMCIA

card

or

installation

of

an

incompatible

 

 

card.

 

 

 

 

 

 

 

 

 

 

 

Ÿ

Damage

due

to

foreign

material

in

the

FDD

or

 

FDD

bay.

 

 

 

 

 

 

 

 

 

 

Ÿ

Damage

the diskette drive cover or inserting diskettes with

 

multiple

labels.

 

 

 

 

 

 

 

 

 

Ÿ

Diskette eject

button

was

bent

or

damaged.

ŸDamage to the CD-ROM drive caused by

excessive

force shocked

or dropped.

Ÿ Fuse blown

by attaching

non-supported devices.

ŸComputer or hard disk could not be used

because the password was forgotten.

If the following symptoms are present, they could indicate the damage was caused by non-warranted activity:

ŸMissing parts can be a symptom of unauthorized

service or modification.

ŸHDD spindles can become noisy if subjected to

excessive force or if dropped.

ŸErrors can be caused by exposure to strong magnetic fields.

How

to

Use

Error

Messages:

 

Use the error

 

 

 

 

codes or messages 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

41.

 

 

 

 

 

 

 

 

 

 

 

 

 

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.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Passwords:

The

Passwords

are security

features

that

are used to protect the system and the hard disk data from

unauthorized

access. There are two

types

of

passwords:

Ÿ

User Password

 

 

 

Ÿ

Supervisor Password

 

 

 

How to Disable

the Passwords

Authorized

Dealer for

this procedure.

Use the following procedure as a guide for computer problems.

Note: The diagnostic tests are intendedonly IBMto test products. Non-IBM products, prototype cards, or modified

options

can

give

false

errors

and invalid

system

responses.

1. Obtain the failing symptoms in as much detail as

possible. Pay

close

attention to

the

error

messages

on

the

screen.

 

 

 

 

 

 

 

 

 

 

2. Verify the symptoms by attempting to recreate the

failure

by

 

running

the

diagnostic

test or

by

repeating

the

 

same

operation.

 

 

 

 

 

 

 

 

 

Note:

To

run the diagnostics, refer to “How to Run

intermittently, use

the

loop

 

option

to

repeat

the

test.

 

 

 

 

 

4.

FRUs

should

not

be

replaced

because

of

a

single,

 

un-reproducible failure. Single

failures

can

occur

from

 

a variety of reasons that have nothing to do with a

 

hardware defect such as electrostatic discharge or

 

software errors. FRU replacement should only be

 

 

considered

when a recurring problems exits.

 

 

Flash Memory:

 

 

BIOS, system setup programs, and

Checking the

AC

Adapter:

You are here

because

the

computer

fails only when the AC Adapter is

used.

 

 

 

ŸIf the power problem occurs only when the port

replicator

is

used,

replace the replicator.

 

Ÿ If the power-on indicator does

not

turn on,

check the

power cord

of

the

AC Adapter

for

correct

continuity

and installation.

 

 

 

 

ŸIf the operational charge does not work, go to “Checking Operational Charging” on page 37.

Use the following procedure to check the adapter.

1. Unplug the AC Adapter cable from the computer and

measure

the output

voltage at the plug of the AC

Adapter

cable. See

the following figure.

4. Measure the output voltage of the AC Adapter.

5.If the voltage is still not correct, replace the AC Adapter.

Note: An

audible

noise from the AC Adapter does not

always

indicate

a defective adapter.

Checking Operational Charging: To check

operational charging, use a discharged battery pack or a

battery pack that shows an

amber battery

status indicator

when it is

installed in

the

computer.

 

 

Perform operational charging. If the battery status

indicator turns orange and the battery

charging indicator

turns green

within two

minutes, replace

the

AC Adapter.

Checking the

Battery

Pack:

Battery charging will

not

start

until the Fuel-Gauge

shows

that less than 90% of

the

total

power

remains;

with

this

condition the battery

pack will charge to 100% of its capacity. This protects the battery pack from being over-charged or having a

shortened

life.

 

Before you perform the following

procedure, be sure you

have the

correct battery pack

for this model.

Port

Replicator

Power Overload:

 

 

If power shut

 

 

 

downs occur intermittently when using a port replicator,

suspect an over-current problem. Some devices use more

 

power; if the maximum usage of each device occurs

 

simultaneously, the total current will exceed the limit,

thereby causing

a

power

shut down. Isolate this problem

by removing

one

of

the

devices,

and

use

the

computer

under

 

the

same

condition

to

see

whether

a

power

shut

down occurs. Do this procedure for all devices, then

 

determine

the cause.
