About the Lithium-Polymer Battery
Your LIFEBOOK has an internal Lithium-Polymer battery that provides power for operating your system 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 43.
The Lithium-Polymer battery operating time may become shorter if it is used under the following conditions:
• Your system is set to use Power Saver 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
“Power Indicator” on page 20.
Recharging the Battery
If you want to know the condition of the Lithium-Polymer battery, check the Battery Level indicator located on the
Status Indicator panel. The indicator changes as the battery level changes.
The Lithium-Polymer battery is recharged internally using the AC adapter or Auto/Airline adapter. To recharge the
battery, simply connect the AC or Auto/Airline adapter.
THE INTERNAL LITHIUM-POLYMER BATTERY CAN ONLY BE REPLACED BY AN AUTHORIZED FUJITSU TECHNICIAN. ANY ATTEMPT BY THE END-USER TO
ACCESS AND REPLACE THE BATTERY MAY RESULT IN DAMAGE TO THE SYSTEM. REMOVAL OF THE COMPONENT COVER BY THE END-USER WILL VOID THE
SYSTEM WARRANTY. FOR ASSISTANCE, GO TO http://solutions.us.fujitsu.com/www/content/support/contact/index.php
ACTUAL BATTERY LIFE WILL VARY BASED ON SCREEN BRIGHTNESS, APPLICATIONS, POWER MANAGEMENT SETTINGS, BATTERY CONDITION AND OTHER
CUSTOMER PREFERENCES. EXTERNAL OPTICAL 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 CONTACT YOUR FUJITSU SUPPORT
REPRESENTATIVE TO HAVE IT REPLACED.
