Lithium ion Battery

Your LifeBook P1600 Series notebook has a Lithium ion

battery that provides power for operating your note-

book when no external power source is available. The

battery is durable and long lasting, but should not be

exposed to extreme temperatures, high voltages, chemi-

cals or other hazards.

The Lithium ion battery operating time may become

shorter if it is used under the following conditions:

■

When used at temperatures lower than 41° F (5° C) or

higher than 95° F (35° C). Extreme temperatures not

only reduce charging efficiency, but can also cause

battery deterioration. The Charging icon on the Status

Indicator panel will flash when you try to charge a

battery that is outside its operating temperature range.

See “” on page 14.

■

When using a high current device such as a modem,

CD-ROM drive, or hard drive, using the AC adapter

will conserve your battery life.

RECHARGING THE BATTERY

If you want to know the condition of the Lithium ion

battery, check the Battery Level indicator located on the

Status Indicator panel. The indicator changes as the

battery level changes.

The Lithium ion battery is recharged internally using the

AC adapter or Auto/Airline adapter. To recharge the

battery make sure the battery that needs to be charged is

installed in your notebook and connect the AC or Auto/

Airline adapt

er.

There is no memory effect on the Lithium ion battery,

therefore you do not need to discharge the battery

completely before recharging. The charge times will be

longer if your system is in use while the battery is

charging. If you want to charge the battery more quickly,

put your system into Standby mode, or turn it off while

the adapter is charging the battery. See “Power Manage-

ment” on page 34.

Low Battery State

When the battery is running low, the Battery Level indi-

cator will glow red. If you do not respond to the low

battery alarm, the batteries will continue to discharge

until they are too low to operate. Your notebook will

then go into Standby mode to try and protect your data

for as long as possible. There is no guarantee that your

data will not be lost once the system reaches this point.

■

Do not leave a faulty battery in your sys-

tem. It may damage your AC adapter,

optional Auto/Airline adapter, or your

notebook itself. It may also prevent

operation of your notebook by draining

all available current into the bad battery.

■

Under federal, state, or local law it may

be illegal to dispose of batteries by

putting them in the trash. Please take

care of our environment and dispose of

batteries properly. Check with your local

government authority for details

regarding recycling or disposing of old

batteries. If you cannot find this infor-

mation elsewhere, contact your support

representative at 1-800-8Fujitsu.

Actual battery life will vary based on

screen brightness, applications, features,

power management settings, battery

condition and other customer preferences.

CD-ROM drive or hard drive usage may

also have a significant impact on battery

life. The battery charging capacity is

reduced as the battery ages. If your

battery is running low quickly, you should

replace it with a new one.

Make sure that the Battery Charging

indicator and the Battery Level indicator

icon on the Status Indicator Panel light.

Using heavy current devices such as a

modem or frequent CD-ROM and

PCMCIA powered external device accesses

may prevent charging completely.

■

Once the low battery indicator appears

you must save all your data and put your

notebook into Standby mode until you

can provide a new power source. You

should provide a charged battery or AC

or Auto/Airline Adapter as soon as pos-

sible.

■

When you are in Standby mode there

must always be at least one power

source active. If you remove all power

sources while your notebook is in

Standby mode, any data that has not

been saved to the hard drive will be lost.
