Power Sources

Your computer h as tw o type s of po w er sources: a L ith ium -Ion

battery or an AC adapter .

CONNECTING THE POWER ADAPTERS

The AC adapter provides power for operating your notebook PC and

charging the battery.

Connecting the AC Adapter

1. Plug t he DC output cab l e into the DC power jack of y our notebook
PC.

2. Plug the AC adapter into an AC electrical outlet.

Switching from AC Adapter Power to Battery
Power

1. Be sure that you have at least one charged battery installed.

2. Remove the AC adapter. Your notebook will automatically switch
from DC power to battery power.

Note: The Lithium-Ion battery is not charged upon purchase. Initially, you
will nee d to conn ect the AC adapter to us e you r notebook PC.

20

RECHARGING THE BATTERY

The Lithium-Ion bat tery is recharged intern ally using t he AC adapter. To
recharge the battery, make sure the battery is installed and the computer is
connected to the AC adapter. There is no "memory effect" in Lithium-Ion
batteries; the re fore, you do not need to disch arge th e ba ttery completely
before recharging. The charge times will be significantly longer if your
notebook PC is in use while the battery is charging. If you want to charge
the battery more quickly, put your computer into Suspend mode or turn it
off while the adapter is charging the battery.

Low Battery State

When the battery charge is low, a notification message appears. If you do
not respo nd to the low batter y m essag e, the batte ry continues to discharge
until it is too low to operate. When this happens, your notebook PC goes
into Suspend mode. There is no g uar an tee y our data will be saved onc e th e
notebook reaches this point.

Caution: To protect your notebook from damage, use only the power
adapter that came with it because each power adapter has its own power
output rating.

Once your notebook PC goes into Suspend mode as a result of a

dead battery, you will be unable to resume operation until you provide a
source of power either from an adapter or a charged battery. Once you
have provided power, you can press the S uspend / R e s ume button to
resu me operation. In Suspend mode, your data is ma intained for some
time, but if a power source is not provided promptly, the Power indicator
stops flashing and then goes out, in which case you have lost the data that
was no t saved. Once you provide power, you can continue to use your
computer while an adapter charges the battery.

21

Battery Replacement

There is danger of explosion if an incorrect battery type is used for
replacement. For computers equipped with a replaceable lithium-ion ba tte ry
pack, the following applies:

• If the battery is placed in an OPERATOR ACCESS AREA, there shall
be a ma r k ing close to the b attery , or a sta tement in both the
opera t ing and the servicing i nstruct i ons;

• If the battery is placed elsewhere in the computer, t h ere shall b e a
marking close to the battery or a statement in the servicing
instructions. The marking or statement shall include the following or
similar t ext:

Caution: Risk of explosion if battery is replaced with an incorrect type.
Dispose of used batteries according to the instructions.

Standby and hiberna tio n

Standby and hibernation are energy-saving features that conserve

power and reduce startup time. They can be initiated by you or by the
system. For more information, refer to "Initiating standby, hibernatio n o r
shutdown."

Standby

CAUTION: To avoid a complete battery discharge, do not leave the
computer in standby for ext ended periods. Connect the computer to an
external power source.

Standby reduces power to system components that are not in use.

When standby is initiated, your work is stored in random access memory
(RAM), and then the screen is cleared. When the computer is in standby,

22

the power lights blink. When you resume from standby, your work returns
to th e screen where you left off.

CAUTION: To reduce the risk of information loss, save your work before
initiating standby.

Hibernation

CAUTION: If the configuration of the computer is changed during
hibernation, resuming from hibernation may not be possible. When the
computer is in hibernation: Do not connect the computer to or disconnect
the c ompute r from an e xpansion product . Do not add or r emove mem ory
modules. Do not insert or remove any hard driv es or optical drives. Do not
connect or disconnect external devices. Do not insert o r rem ove an ex t ern al
media card , s uch as a MultiMed iaCard.

Hibernation saves your work to a hibernation file on the hard drive,

and then shuts down the computer. The power lights are turned off. When
you restore from hibernation, your work returns to the screen wher e you
left off. If a power-on password has been set, the password must be
entered to res tor e fr o m hib ernation.

CAUTION: To reduce the risk of information loss, save your work before
initiating hibernation.

You can disa b le hibe rnation. However, if hibernation is disabled and

the system reaches a lowba tt er y co nd ition, the sy s tem will not a u tomaticall y
save your work while power is on or when standby has been initiated.

Initiating standby, hibernation or shutdown

The following sections explain when to initiate stan dby or

hibernation and when to shut down the computer.

23

NOTE: Y ou c annot initiate an y type of n etworking communi c ations or
perfo rm an y computer functi ons wh i l e th e com pute r is i n sta ndby or
hibernation.

When you leave your work

When standby is initiated, your work is stored in random access

memory (RAM), and then the screen is cleared. When the computer is in
standby, it uses less power than when it is on. Your work returns instantly
to th e screen when you re s ume from sta ndby. Hibernation saves your work
to a hibernation file on the hard drive, and then shuts down the computer.

When the com pute r is in hi b e rn at i on, it uses much les s power than

when it is in standby. When the computer will be unused and disconnected
from external power for an extended period, shut down the computer and
remove the battery pack to extend the life of the battery pack. For details
on battery pack storage, refer to "Storing a battery pack."

When a reliable power supply is unavailable

Be sure that hibernation remains enabled, especially if you are

operating the computer on battery power and do not have access to an
external power supply. If the battery pack fails, hibernation saves your work
to a hibernation file and shuts down the computer. It is recommended that
if you pause your work when the power supply is uncertain, you take one of
the followin g actions :

• Save your work, and then initiate standby.

• Initiate hibernation.

• Shut down the computer.
