Dead Battery Suspend mode shows on the Status indi- cator just like the normal Sleep mode. Once your Life- Book notebook goes into Dead Battery Suspend mode you will be unable to resume operation until you provide a source of power from an AC adapter. 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 main- tained 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 LifeBook notebook while the adapter is charging the battery.
Shorted Batteries
The Status Indicator panel displays the battery status via the Battery Status indicator to show the charge level available in that battery. If the display is flashing red, it means that the battery is damaged and must be replaced so it does not damage any other parts of your LifeBook notebook.
