v

If

you

are

instructed

to

replace

a

FRU

but

the

replacement

does

not

correct

the

problem,

reinstall

the

original

FRU

before

you

continue

.

v

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

replacing

one

of

them

does

not

correct

the

problem,

reinstall

that

board,

and

then

replace

the

other

one.

v

If

an

adapter

or

a

device

consists

of

more

than

one

FRU,

any

of

the

FRUs

may

be

the

cause

of

the

error.

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:

The

setup

configuration

on

the

computer

you

are

servicing

may

have

been

customized.

Running

Automatic

Configuration

may

alter

the

settings.

Note

the

current

configuration

settings

(using

the

View

Configuration

option);

then,

when

service

has

been

completed,

verify

that

those

settings

remain

in

effect.

Strategy

for

replacing

a

hard

disk

drive

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

may

have

been

changed.

Be

extremely

careful

during

write

operations

such

as

copying,

saving,

or

formatting.

If

you

select

an

incorrect

drive,

data

or

programs

can

be

overwritten.

Important

notice

for

replacing

a

system

board

Some

components

mounted

on

a

system

board

are

very

sensitive.

Improper

handling

of

a

system

board

can

cause

damage

to

those

components,

and

may

cause

a

system

malfunction.

Attention:

When

handling

a

system

board:

v

Do

not

drop

a

system

board

or

apply

any

excessive

force

to

it.

v

Avoid

rough

handling

of

any

kind.

v

Avoid

bending

a

system

board

and

hard

pushing

to

prevent

cracking

at

each

BGA

(Ball

Grid

Array)

chipset.

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

causes

the

first

error

code

may

also

cause

false

error

codes.

If

no

error

code

is

displayed,

see

whether

the

error

symptom

is

listed

in

the

Symptom-to-FRU

Index

for

the

computer

you

are

servicing.

Strategy

for

replacing

FRUs

for

Custom

Model

Variant

(CMV)

products

Custom

Model

Variant

(CMV)

is

a

unique

configuration

that

has

been

negotiated

between

Lenovo

TM

and

the

customer.

A

unique

4-digit

MT

and

3-digit

model

is

provided

to

the

customer

to

place

orders

(Example:

1829-W15).

A

CMV

is

a

special

bid

offering.

Therefore,

it

is

NOT

generally

announced.

There

are

three

information

resources

to

identify

which

FRUs

are

used

to

support

CMV

products.

These

sources

are

PC

Entitlement

Warehouse

(PEW),

eSupport,

and

the

HMM.
