LifeBook B 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 2-10 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
Your LifeBook B Series 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 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 LifeBook and disconnect
the AC adapter.
3. Slide the Battery Bay Lock to the right, then slide the
battery release button in the same direction.
4. Slide the battery away from the battery bay and
remove it from the bay.
5. Position the new battery on the tray slides and care-
fully slide it fully into the tray. (Figure 4-2)
6. Slide the Battery Bay Lock to the left to lock the pack
into position.
7. Plug in the AC adapter and turn the power on.

data that has not been saved to the hard drive will be
lost.
