generate

 

heat

 

when

 

turned

 

on

 

and

 

when

 

batteries

 

are

 

charging.

 

Notebook

 

PCs

 

can

 

generate

 

a

 

significant

 

amount

 

of

 

heat

 

due

 

to

 

their

 

compact

 

size.

 

Always

 

follow

 

these

 

basic

 

precautions:

 

v

   

Do

 

not

 

leave

 

the

 

base

with

 

your

 

lap

 

or

 

any

 

part

 

of

 

your

 

body

 

for

 

an

 

extended

 

period

 

when

 

the

 

computer

 

is

 

functioning

 

or

 

when

 

the

 

battery

 

is

 

charging.

 

Your

 

computer

 

produces

 

some

 

heat

 

during

 

normal

 

operation.

 

Extended

 

contact

 

with

 

the

 

body

 

could

 

cause

 

discomfort

 

or,

 

potentially,

 

a

 

skin

 

burn.

 

v

   

Do

 

not

 

operate

 

your

 

computer

 

or

 

charge

 

the

 

battery

materials

 

or

 

in

 

explosive

 

environments.

 

v

sinks

 

are

 

provided

 

with

 

the

 

product

 

for

 

safety,

 

comfort,

 

and

 

reliable

 

operation.

 

These

 

features

 

might

 

inadvertently

 

become

 

blocked

 

by

 

placing

 

the

 

product

 

on

 

a

 

bed,

 

sofa,

 

carpet,

 

or

 

other

 

flexible

 

surface.

 

Never

 

block,

 

cover

 

or

 

disable

 

these

 

features.

You

 

should

 

inspect

 

your

 

desktop

 

computer

 

for

 

dust

 

accumulation

 

at

 

least

 

once

 

every

 

three

 

months.

 

Before

from

 

vents

 

and

 

perforations

 

in

 

the

 

bezel.

 

If

 

you

 

notice

 

external

 

dust

 

accumulation,

 

you

 

should

 

also

 

examine

 

and

 

remove

 

dust
