- 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
Tablet PC will go into Sleep mode. There is no guarantee that your data will be saved once the Tablet PC reaches this
point.
Dead Battery Suspend mode shows on the Status indicator just like the normal Sleep mode. Once your Tablet PC 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 slide 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 Tablet PC while an adapter is charging the battery.
Shorted Batteries
The Status Indicator panel indicator associated with the Battery Level indicator displays the operating level available
in that battery. If this display shows a flashing red LED, it means the battery is damaged and must be replaced so it
does not damage other parts of your LIFEBOOK Tablet PC.
USING HEAVY CURRENT DEVICES OR FREQUENT EXTERNAL OPTICAL DRIVE ACCESSES MAY PREVENT CHARGING COMPLETELY.
• ONCE THE LOW BATTERY NOTIFICATION MESSAGE APPEARS, YOU NEED TO SAVE ALL YOUR ACTIVE DATA AND PUT YOUR LIFEBOOK TABLET PC INTO
S
LEEP MODE UNTIL YOU CAN PROVIDE A NEW POWER SOURCE. YOU SHOULD PROVIDE A CHARGED BATTERY, AN AC POWER ADAPTER, OR
A
UTO/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 T
ABLET PC IS IN SLEEP MODE, ANY DATA THAT HAS NOT BEEN SAVED TO THE HARD DRIVE WILL BE LOST.
