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.
