Dead Battery Suspend mode shows on the Status indi-
cator just like the normal Suspend mode. Once your
LifeBook 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 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-
11 on page 13) 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.

REPLACING THE BATTERY

With the purchase of an additional battery, you can have
a fully charged spare to swap with one that is not
charged. There are two ways to swap batteries, cold-
swapping and warm-swapping:
