Cabin S Series.book manual Lithium Ion Battery, Recharging the Batteries

Lithium Ion Battery

Your Fujitsu LifeBook notebook has a Lithium Ion battery that provides power for operating your 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 temp- erature range. (See Battery Charging Indicators on page 17 for more information)

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

C A U T I O N

Actual battery life will vary based on screen brightness, applications, features, power management settings, battery condition and other customer preferences. DVD drive, CD-RW Drive, 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.

C A U T I O N

Do not leave a faulty battery in your notebook. It may damage your AC adapter, optional Auto/Airline adapter, another battery or your notebook itself. It may also prevent operation of your notebook by draining all available current into the bad battery.

C A U T I O N

Under federal, state, or local law it may be illegal to dis- pose 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 bat- teries. 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 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 is installed in your notebook and connect the AC or Auto/Airline adapter.

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 notebook is in use while the battery is charging. If you want to charge the battery more quickly, put your notebook into Suspend mode, or turn it off while the adapter is charging the battery. (See Power Management on page 36 for more information on Suspend mode and shutdown procedure)

C A U T I O N

Using heavy current devices such as Modem or frequent DVD/CD-RW/CD-ROM accesses may prevent charging completely.
