RECHARGING THE BATTERIES
If you want to know the condition of the
primary Lithium ion battery, check the
Battery Status indicator located on the
Status Indicator panel. The indicator
changes as the battery level changes.
The Lithium ion battery is recharged inter-
nally using the AC adapter. To recharge the
battery make sure the battery that needs to
be charged is installed in your LifeBook
notebook and connect the AC adapter
.
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
significantly longer if your LifeBook note-
book is in use while the battery is charging.
If you want to charge the battery more
quickly, put your LifeBook into Suspend
mode, or turn it off while the adapter is
charging the battery.
Low Battery State
When the battery is running low, a low
battery notification message will appear. If
you do not respond to the low battery
message, the batteries will continue to
discharge until they are too low to operate.
When this happens, your LifeBook note-
book will go into Suspend mode. There is
no guarantee that your data will not be lost
once the notebook reaches this point
.
Note that you can change the state in which
the battery goes into Suspend mode in the
Power properties of the Control Panel.
Dead Battery Suspend mode shows on the
Status indicator just like the normal
Suspend mode. Once your LifeBook note-
book goes into Dead Battery Suspend
mode you will be unable to resume opera-
tion until you provide a source of power
from an AC adapter. Once you have
Make sure the Battery
Charging indicator and the
percentage charge is shown
inside the Battery Status icon
on the Status Indicator
Panel.
Using high current devices
such as a modem or
frequent optical drive
accesses may prevent
complete charging.
To prevent loss of data, you
should save all your active
data and put your notebook
into Suspend mode when the
low battery message
appears, until you can
provide a new power source.
When you are in Suspend
mode, there must always be
at least one power source
active. If you turn off the
power with the power/
suspend/resume button, or
remove all power sources
while your notebook is in
Suspend mode, any data that
has not been saved to the
hard drive will be lost. You
should provide power to your
notebook from an AC power
adapter as soon as possible.
