Removing

and

replacing

the

battery

Your

computer

has

a

special

type

of

memory

that

maintains

the

date,

time,

and

settings

for

built-in

features,

such

as

parallel-port

assignments

(configuration).

A

battery,

sometimes

called

the

CMOS

battery,

keeps

this

information

active

when

you

turn

off

the

computer.

The

battery

normally

requires

no

charging

or

maintenance

throughout

its

life;

however,

no

battery

lasts

forever.

If

the

battery

fails,

the

date,

time,

and

configuration

information

(including

passwords)

are

lost.

An

error

message

is

displayed

when

you

turn

on

the

computer.

Refer

to

“Lithium

battery

notice”

on

page

x

for

information

about

replacing

and

disposing

of

the

battery.
