Under federal, state or local law it may
be illegal to dispose of batteries by
putting them in the trash. Please take
care of our environment and dispose
of batteries properly. Check with your
local government authority for details
regarding recycling or disposing of
old batteries. If you cannot find this
information elsewhere, contact your
support representative at 1-800-
8FUJITSU (1-800-838-5487).
Shorted Batteries
If your Status Indicator panel shows a shorted
battery, check the installation for that battery by
removing and re-installing it. If it still shows
that it is shorted, replace it with a new battery. The Lithium ion batteries are recharged inter-
nally using the AC adapter or auto/airline
adapter. To recharge the batteries:
■
Make sure the main battery to be charged is
installed in the Battery bay and any optional
second battery is installed in Multi-function
Bay 2 of your notebook,then connect the AC
adapter or auto/airline adapter.
■
Make sure that the Battery Charging indica-
tor to the left of the Battery Level indicator of
the battery to be charged is visible on the
Status Indicator panel.
■
The percentage charge is shown inside the
Battery Level icon. (Figure 2-4 on page 21.)
When two Lithium ion batteries are installed,
the charge/discharge rate of the main and
optional second Lithium ion batteries are the
same,as they are connected in parallel and are
both charging and/or discharging at the same
time. Since the rates are the same, one may fin-
ish charging or discharging before the other if
they were not at the same charge level when
C A U T I O N
Do not leave a faulty battery in your
notebook. It might damage your AC
adapter, optional auto/airline adapter,
another battery, or your notebook itself.
It may also prevent operation of your
notebook by draining all available current
into the bad battery.
C A U T I O N
A shorted battery is damaged and must
be replaced so that it does not damage
anything else.
Recharging the Batteries
If you want to check the condition of either the
main Lithium ion battery or an optional second
Lithium ion battery, check the Battery Level
indicators located on the Status Indicator panel.
These indicators change as the battery levels
change. Battery 1 is the main Lithium ion
battery and Battery 2 is an optional second
Lithium ion battery which is installed in Multi-
function Bay 2 only. (Figure 2-3 on page 19.)
