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.
Dead Battery Suspend mode shows on the Status indicator just like the normal Sleep mode. 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.
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
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 NOTEBOOK IS IN SLEEP MODE, ANY DATA
THAT HAS NOT BEEN SAVED TO THE HARD DRIVE WILL BE LOST.
