- Lithium ion Battery
Low Battery State
When the battery is running low, a low battery notification 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 notebook will go into sleep mode. There is no guarantee that your data will be saved
once the notebook reaches this point.
Once your notebook goes into Dead Battery Suspend mode you will be unable to resume operation until
you provide a source of power either from an adapter, or a charged battery. Once you have provided power,
you will need to press the Power/Suspend/Resume button to resume operation.
In the Dead Battery Suspend mode, your data can be maintained for some time, but if a power source is
not provided promptly, the Power indicator will stop flashing and go out, meaning that you have lost the
data that was not stored. Once you provide power, you can continue to use your notebook while an adapter
is charging the battery.
Shorted Batteries
The Status Indicator panel uses an LED below the battery outline of the Battery Level indicator to display
the operating level available in that battery. If this display shows a Shorted Battery, it means the battery is
damaged and must be replaced so it does not damage other parts of your LifeBook notebook.
USING HEAVY CURRENT DEVICES SUCH AS THE MODEM OR FREQUENT DVD/CD-RW/CD-ROM
ACCESSES MAY PREVENT CHARGING COMPLETELY.
• ONCE THE LOW BATTERY NOTIFICATION MESSAGE APPEARS, YOU NEED TO SAVE ALL YOUR ACTIVE DATA AND PUT
YOUR LIFEBOOK NOTEBOOK INTO SLEEP MODE UNTIL YOU CAN PROVIDE A NEW POWER SOURCE. YOU SHOULD
PROVIDE A CHARGED BATTERY, AN AC POWER ADAPTER, OR AUTO/AIRLINE ADAPTER AS SOON AS POSSIBLE.
• WHEN YOU ARE IN SLEEP MODE THERE MUST ALWAYS BE AT LEAST ONE POWER SOURCE ACTIVE. IF YOU REMOVE
ALL POWER SOURCES WHILE YOUR LIFEBOOK NOTEBOOK IS IN SLEEP MODE, ANY DATA THAT HAS NOT BEEN
SAVED TO THE HARD DRIVE WILL BE LOST.
