LifeBook C Series – Section Four
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-
9 on page 17) 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. (Figure 4-1)
1. Have a charged battery ready to install.
2. Shut down your LifeBook and disconnect
the AC adapter.
3. Slide the battery release panel open.
4. Remove the battery from the bay.
5. Slide the new battery into the bay.
6. Slide the battery release panel close.
7. Plug in the AC adapter and turn the power on.

CAUTION
If the Lithium ion battery connector is not fully seated,
you may not be able to use your LifeBook or charge
your battery.
