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 37.
The Lithium-Polymer 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
“Power Indicator” on page 18.
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
