Important

safety

information

This

information

can

help

you

safely

use

your

IBM

®

personal

computer.

Follow

and

retain

all

information

included

with

your

IBM

computer.

The

information

in

this

document

does

not

alter

the

terms

of

your

purchase

agreement

or

the

IBM

Statement

of

Limited

Warranty.

Customer

safety

is

important

to

IBM.

Our

products

are

developed

to

be

safe

and

effective.

However,

personal

computers

are

electronic

devices.

Power

cords,

power

adapters,

and

other

features

can

create

potential

safety

risks

that

can

result

in

physical

injury

or

property

damage,

especially

if

misused.

To

reduce

these

risks,

follow

the

instructions

included

with

your

product,

observe

all

warnings

on

the

product

and

in

the

operating

instructions,

and

review

the

information

included

in

this

document

carefully.

By

carefully

following

the

information

contained

in

this

document

and

provided

with

your

product,

you

can

help

protect

yourself

from

hazards

and

create

a

safer

computer

work

environment.

Note:

This

information

includes

references

to

power

adapters

and

batteries.

In

addition

to

mobile

personal

computers,

IBM

ships

some

products

(such

as

speakers

or

monitors)

with

external

power

adapters.

If

you

have

such

a

product,

this

information

applies

to

your

product.

In

addition,

your

computer

product

may

contain

a

coin-sized

internal

battery

that

provides

power

to

your

system

clock

even

when

the

machine

is

unplugged,

so

the

battery

safety

information

applies

to

all

computers.

Conditions

that

require

immediate

action

Products

can

become

damaged

due

to

misuse

or

neglect.

Some

product

damage

is

serious

enough

that

the

product

should

not

be

used

again

until

it

has

been

inspected

and,

if

necessary,

repaired

by

an

authorized

servicer.

As

with

any

electronic

device,

pay

close

attention

to

the

product

when

it

is

turned

on.

On

very

rare

occasions,

you

might

notice

an

odor

or

see

a

puff

of

smoke

or

sparks

vent

from

your

machine.

Or

you

might

hear

sounds

like

popping,

cracking

or

hissing.

These

conditions

might

merely

mean

that

an

internal

electronic

component

has

failed

in

a

safe

and

controlled

manner.

Or,

they

might

indicate

a

potential

safety

issue.

However,

do

not

take

risks

or

attempt

to

diagnose

the

situation

yourself.

Frequently

inspect

your

computer

and

its

components

for

damage

or

wear

or

signs

of

danger.

If

you

have

any

question

about

the

condition

of

a

component,

do

not

use

the

product.

Contact

the

IBM

HelpCenter

®

or

the

product

manufacturer

for

instructions

on

how

to

inspect

the

product

and

have

it

repaired,

if

necessary.

In

the

unlikely

event

that

you

notice

any

of

the

conditions

listed

below,

or

if

you

have

any

safety

concerns

with

your

product,

stop

using

the

product

and

unplug

it

from

the

power

source

and

telecommunication

lines

until

you

can

speak

to

the

IBM

HelpCenter

for

further

guidance.

General

safety

guidelines

Always

observe

the

following

precautions

to

reduce

the

risk

of

injury

and

property

damage.

Service

Do

not

attempt

to

service

a

product

yourself

unless

instructed

to

do

so

by

the

IBM

HelpCenter.

Use

only

an

IBM

authorized

service

provider

who

is

approved

to

repair

your

particular

product.

Note:

Some

parts

can

be

upgraded

or

replaced

by

the

customer.

These

parts

are

referred

to

as

Customer

Replaceable

Units,

or

CRUs.

IBM

expressly

identifies

CRUs

as

such,

and

provides

documentation

with

instructions

when

it

is

appropriate

for

customers

to

replace

those

parts.

You

must

closely

follow

all

instructions

when

performing

such

replacements.

Always

make

sure

that

the

power

is

turned

off

and

that

the

product

is

unplugged

from

any

power

source

before

you

attempt

the

replacement.

If

you

have

any

questions

or

concerns,

contact

the

IBM

HelpCenter.

Power

cords

and

power

adapters

Use

only

the

power

cords

and

power

adapters

supplied

by

the

product

manufacturer.

Never

wrap

a

power

cord

around

the

power

adapter

or

other

object.

Doing

so

can

stress

the

cord

in

ways

that

can

cause

the

cord

to

fray,

crack

or

crimp.

This

can

present

a

safety

hazard.

Always

route

power

cords

so

that

they

will

not

be

walked

on,

tripped

over,

or

pinched

by

objects.

Protect

the

cord

and

power

adapters

from

liquids.

For

instance,

do

not

leave

your

cord

or

power

adapter

near

sinks,

tubs,

toilets,

or

on

floors

that

are

cleaned

with

liquid

cleansers.

Liquids

can

cause

a

short

circuit,

particularly

if

the

cord

or

power

adapter

has

been

stressed

by

misuse.

Liquids

can

also

cause

gradual

corrosion

of

the

power

cord

terminals

and/or

the

connector

terminals

on

the

adapter

which

can

eventually

result

in

overheating.

Always

connect

power

cords

and

signal

cables

in

the

correct

order

and

ensure

that

all

power

cord

connectors

are

securely

and

completely

plugged

into

receptacles.
