The rate at which you use battery power determines how long you can use the battery of your computer between charges. As each computer user has different habits and needs, it is difficult to predict how long a battery charge will last. There are two main factors: v The amount of energy stored in the battery when you begin to work. v The way you use your computer: for example, how often you access the hard disk drive and how bright you make the computer display. Using the AC adapter The power to run your computer can come either from the lithium-ion (Li-ion) battery pack provided with it, or from AC power through the AC adapter. While you use AC power, the battery charges automatically. The AC adapter that comes with your computer has two basic components: 1. The transformer pack that converts AC power for use with the computer. 2. The power cord that plugs into the AC outlet and into the transformer pack. CAUTION Using an improper power cord could cause severe damage to your computer. To use the AC adapter, do the following. Be sure to take these steps in the order in which they are given here. 1. Connect the AC adapter to the AC power adapter jack of the computer. 2. Connect the power cord to the transformer pack. Chapter 2. Using your computer 31

The
rate
at
which
you
use
battery
power
determines
how
long
you
can
use
the
battery
of
your
computer
between
charges.
As
each
computer
user
has
different
habits
and
needs,
it
is
difficult
to
predict
how
long
a
battery
charge
will
last.
There
are
two
main
factors:
v
The
amount
of
energy
stored
in
the
battery
when
you
begin
to
work.
v
The
way
you
use
your
computer:
for
example,
how
often
you
access
the

drive
and
how
bright
you
make
the
computer
display.
Using

provided
with
it,
or
from
AC
power
through
the
AC
adapter.
While
you
use
AC
power,
the
battery
charges
automatically.
The
AC
adapter
that
comes
with
your
computer
has
two
basic
components:
1.
The
transformer
pack
that
converts
AC
power
for
use
with
the
computer.
2.
The
power
cord
that
plugs
into
the
AC
outlet
and
into
the
transformer
pack.
CAUTION
Using
an
improper
power
cord
could
cause
severe
damage
to
your
computer.
To
use
the
AC
adapter,
do
the
following.
Be
sure
to

these
steps
in
the

given
here.
