When you are in Suspend mode there must always be
at least one power source active. If you turn off the
power with the power switch, or remove all power
sources while your LifeBook notebook is in Suspend
mode, any data that has not been saved to the hard
drive will be lost.
Dead Battery Suspend mode shows on the Status indi-
cator just like the normal Suspend mode. Once your
LifeBook 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 LifeBook notebook while an
adapter is charging the battery.
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.
(See Figure 2-10 on page 15) If this display shows a
Shorted Battery, it means that the battery is damaged
and must be replaced so it does not damage any other
parts of your LifeBook notebook.
