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.
Replacing the Battery

charged. There are two ways to swap batteries, cold-swapping and hot-swapping:
