Lithium ion Battery

Your Fujitsu LifeBook notebook has a Lithium ion battery that provides power for operating your LifeBook notebook when no external power source is available. The battery is durable and long lasting, but should not be exposed to extreme temperatures, high voltages, chemicals or other hazards.

The Lithium ion battery operating time may become shorter if it is used under the following conditions:

■When used at temperatures that exceeds a low of 5°C or a high of 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 Battery Charging Indicator on page 14 for more information)

■When using a high current device such as a modem, DVD, or hard drive, using the AC adapter will conserve your battery life.

C A U T I O N S

■Actual battery life will vary based on screen bright- ness, applications, features, power management set- tings, battery condition and other customer preferences. Media player 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.

■Do not leave a faulty battery in your LifeBook note- book. It may damage your AC adapter, optional Auto/Airline adapter, a second battery or your Life- Book notebook itself. It may also prevent operation of your LifeBook notebook by draining all available cur- rent 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 information elsewhere, contact your support representative at 1- 800-8Fujitsu (1-800-838-5487).

RECHARGING THE BATTERIES

If you want to know the charge condition of the primary 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

L i t h i u m i o n B a t t e r y

is installed in your LifeBook notebook and connect the AC or Auto/Airline adapter. The Lithium ion battery can also be charged using an external battery charger, avail- able from Fujitsu.

P O I N T

Make sure that the Battery Charging indicator and the percentage charge is shown inside the Battery Level icon on the Status Indicator Panel.

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 significantly longer if your LifeBook notebook is in use while the battery is charging. If you want to charge the battery more quickly, put your LifeBook notebook into Suspend mode, or turn it off while the adapter is charging the battery. (See Power Management on page 30 for more information on Suspend mode and shutdown procedure)

C A U T I O N

Using heavy current devices such as a Modem or frequent media player accesses may prevent charging completely.

Low Battery State

When the battery is running low, a low battery notifica- tion message will appear. If you do not respond to the low battery message, the batteries will continue to discharge until they are too low to operate. When this happens, your LifeBook notebook will go into Suspend mode. There is no guarantee that your data will be saved once the notebook reaches this point.

C A U T I O N S

■Once the low battery notification message appears, you need to either plug in an AC power adapter or Auto/Airline adapter, or save all your active data, power down your system, and install a charged battery as soon as possible.

■When you are in Suspend mode there must always be at least one power source active. If you turn off the power with the power switch, or remove all power sources while your LifeBook notebook is in Suspend mode, any data that has not been saved to the hard drive will be lost.

Dead Battery Suspend mode shows on the Status indi- cator just like the normal Suspend mode. Once your LifeBook notebook goes into Dead Battery Suspend mode you will be unable to resume operation until you
