70 - 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 Standby 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 Standby 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 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 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 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 NOTEBOOK INTO STANDBY 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 STANDBY MODE THERE MUST ALWAYS BE AT LEAST ONE POWER SOURCE ACTIVE. IF YOU
REMOVE ALL POWER SOURCES WHILE YOUR LIFEBOOK NOTEBOOK IS IN STANDBY MODE, ANY DATA THAT HAS NOT
BEEN SAVED TO THE HARD DRIVE WILL BE LOST.
