Lithium ion Battery

Your LifeBook Tablet PC has a Lithium ion battery that provides power for operating your Tablet PC 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 exceed a low of 5°C or a high of 35°C (41° to 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.
• When using a high current device such as a modem, external optical drive, or the hard drive, using
the AC adapter will conserve your battery life.
