Dead Battery Suspend mode shows on the Status indi-
cator just like the normal Standby mode. Once your
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 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 12) 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 notebook.

REPLACING THE BATTERY

Your LifeBook B Series notebook comes with two
battery packs: one installed and one spare. By keeping
the spare battery fully charged, you can immediately
swap with one that is not charged. There are two ways to
swap batteries: cold-swapping and warm-swapping.
Cold swapping means swapping batteries when the
system has been powered down; warm swapping is
performed when the system is in Standby mode.
Cold-swapping Batteries
To cold-swap batteries in your battery bay follow these
easy steps: (Figure 4-1)
1. Have a charged battery ready to install.
2. Shut down your notebook and disconnect
the AC adapter.
