Lithium ion Battery
Your Fujitsu LifeBook notebook has a Lithium ion battery that provides power for operating your note- book when no external power source is available. The rechargeable battery is durable and long lasting, but should not be exposed to extreme temperatures, high voltages, chemicals or other hazards. For information on maximizing your battery life, refer to the section entitled “Power Management” on page 30.
The Lithium ion battery operating time may become shorter if it is used under the following conditions:
■Your system is set to use the Max Battery power scheme when running on battery power. If you change the power scheme to a different profile, your battery life may vary.
■When used at temperatures that exceed a low of 5°C (40°F) or a high of 35°C (95°F). 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 15 for more information)
■When using a high current device such as a modem,
■Do not leave a faulty battery in your LifeBook notebook. It may damage your AC adapter or your notebook itself. It may also prevent operation of your 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 put- ting 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:
Actual battery life will vary based on factors such as screen brightness, applications, features, power management settings, battery condition and other customer preferences.

RECHARGING THE BATTERIES
If you want to know the condition of the primary Lithium ion battery, check the Battery Status 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. To recharge the battery make sure the battery that needs to be charged is installed in your Life- Book notebook and connect the AC adapter.
Make sure the Battery Charging indicator and the percentage charge is shown inside the Battery Status 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 into Sleep mode, or turn it off while the adapter is charging the battery. (See Power Management on page 30 for more information on Sleep mode and shutdown procedure)
Using high current devices such as a modem or frequent optical drive accesses may prevent complete charging.
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 Sleep mode. There is no guarantee that your data will not be lost once the notebook reaches this point.
Note that you can change the state in which the battery goes into Sleep mode in the Power properties of the Control Panel.
To prevent loss of data, you should save all your active data and put your notebook into Sleep mode when the low battery message appears, until you can provide a new power source. When you are in Sleep mode, there must always be at least one power source active. If you turn off the power with the power/suspend/resume button, or remove all power sources while your notebook is in Sleep mode, any data that has not been saved to the hard drive will be lost. You should provide power to your notebook from an AC power adapter as soon as possible.
