Lithium ion Battery
Your LIFEBOOK notebook has a Lithium ion battery that provides power for operating your notebook 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 40.
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
“Power Indicator” on page 20.
•
When using a high current device such as an optical drive or hard drive, using the AC adapter will conserve your
battery life.
