Replacing The Battery - Fujitsu LifeBook N series User Manual

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
notebook will go into Suspend mode. There is
no guarantee that your data will be saved once
the notebook reaches this point.
Once the low battery notification message
appears, you need to either plug in an
AC power adapter, or save all your active
data, power down your system, and install
a charged battery as soon as possible.
When you are in Suspend mode there
must always be at least one power source
active. If you remove all power sources
while your LifeBook notebook is in
Suspend mode, any data that has not
been saved to the hard drive will be lost.
Once your LifeBook notebook battery goes dead,
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 Power/Suspend/
Resume button to resume operation. If your
battery dies, your data will be lost if a power
source is not provided promptly. Once you
provide power, you can continue to use your
LifeBook notebook while an adapter is charging
the battery.
Damaged Batteries
The Battery Level indicator displays the operating
level available in that battery. If this icon is red
and blinking, it means that the battery is damaged
and must be replaced so it does not damage any
other parts of your notebook.
