65
- Lithium ion Battery
Low Battery State
When the battery is running low, your notebook will beep every 15 seconds and the Battery Level
indicator will flash. If you do not respond to the low battery alarm, the batteries will continue to discharge
until they are too low to operate. When this happens there will be a multiple beep alarm and the Battery
Level indicator will show a dead battery. Your LifeBook will then go into Standby mode to try to protect
your data for as long as possible. There is no guarantee that your data will not be lost once the notebook
reaches this point.
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 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.
Shorted Batteries
The Status Indicator panel uses an LED below 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.
