- Polymer 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, your data can be maintained for some time, but if power is not provided
promptly, the Power indicator will stop flashing and go out, resulting in loss of 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 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 notebook.
