Recharging The Battery; Replacing The Battery - Fujitsu Lifebook P1510 User Manual

RECHARGING THE BATTERY

If you want to know the condition of the
Lithium ion battery, check the Battery Level
indicator located on the Status Indicator
panel. The indicator changes as the battery
level changes.
The Lithium ion battery is recharged
internally using the AC adapter. To recharge
the battery make sure the battery that
needs to be charged is installed in your
notebook and connect the AC.
Make sure that the Battery
Charging indicator and the
Battery Level indicator icon on
the Status Indicator Panel light.
There is no memory effect on the Lithium
ion battery, therefore you do not need to
discharge the battery completely before
recharging. The charge times will be longer
if your notebook is in use while the battery
is charging. If you want to charge the
battery more quickly, put your notebook into
Standby mode, or turn it off while the
adapter is charging the battery.
Using heavy current devices
such as a modem or frequent
CD-ROM and PCMCIA powered
external device accesses may
prevent charging completely.
Low Battery State
When the battery is running low, the Battery
Level indicator will glow red. If you do not
respond to the low battery alarm, the
batteries will continue to discharge until
they are too low to operate. Your notebook
will then go into Standby mode to try and
protect your data for as long as possible.
There is no guarantee that your data will not
be lost once the notebook reaches this
point.

■ Once the low battery
indicator appears you must
save all your data and put
your notebook into Standby
mode until you can provide a
new power source. You
should provide a charged
battery or AC Adapter as
soon as possible.
■ When you are in Standby
mode there must always be
at least one power source
active. If you remove all
power sources while your
notebook is in Standby mode,
any data that has not been
saved to the hard drive will be
lost.
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 note-
book while an adapter is charging the
battery.

REPLACING THE BATTERY

Your LifeBook P Series notebook comes
with one battery pack; you might want to
consider purchasing a spare. By keeping a
spare battery fully charged, you can
immediately swap with one that is not
charged.
