Charging The Battery; Removing And Installing The Battery - Fujitsu Stylistic Manual

CHARGING THE BATTERY

The Stylistic battery can be charged while it is
installed in the Tablet PC.
To do so:
1. Connect a DC power source, such as the AC
adapter, to the DC input connector on the
Tablet PC. The DC Input icon appears in the
Status display. If the battery charge is below
90%, the battery begins charging and the
Charging icon appears in the Status display.
If the battery charge is 90% or higher when
you connect DC power, the battery will not
charge, preventing battery overcharging.
2. Look at the Battery Gauge icon in the Status
display to determine the percentage of
charge in the battery. See "Status Display" in
Chapter 1 of this manual for a description of
the Battery Gauge icon.
As long as DC power remains connected to the
Tablet PC, the charging process continues until
the battery charge reaches 100%. Charge
times shown in Table 2-2, "Battery Charging
Time" are for a fully discharged battery
charging both while the Tablet PC is and is not
in use.

system without interrupting the charging
process; however, using the system while
the battery is charging will cause the battery
to charge at a slower rate, as noted in Table
2-2, "Battery Charging Time".
• As noted in the procedure above, the system
will not begin charging the battery if the
battery charge level is 90% or higher when
the system is initially connected to external
DC power. (This prevents the battery from
being overcharged.)
• The battery uses Lithium ion battery cells
which have no "memory effect." You do not
need to discharge the battery before you
begin charging.
REMOVING AND INSTALLING THE
BATTERY
The battery can be removed from the Tablet
PC and swapped with a charged battery. To
remove the battery from the Tablet PC:
1. Choose one of the following:
• If a charged battery is available, you can
suspend system operation. A built-in
"bridge" battery will maintain the system in
Suspend-to-RAM mode for about 5
minutes while the battery is removed; this
allows time for replacement with a
charged battery.
• If a charged battery is not available, save
your work and close all running programs,
then shut down the system or Hibernate
(Save-to-Disk).
• Plug in an external DC power source.
2. Slide the battery release latch in the
direction indicated. (See Figure 2-4 for
location).
3. Pull the battery away from the system, as
shown in the illustration and remove the
battery from the Tablet PC.
