- 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.
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 Dead Battery Suspend mode, data can be maintained for a while, but if a power is not provided
promptly, the Power indicator will stop flashing and go out, meaning you have lost the data that was not
stored. Once power is provided, you can use your notebook while an adapter charges the battery.
Shorted Batteries
The Status Indicator panel uses a symbol inside 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.
