Using heavy current devices such as LAN
cards or frequent DVD/CD-ROM accesses
may prevent charging completely.
■
Make sure the percentage charge is shown
inside the Battery Level icon.
(Figure 3-2 on page 21 . )
There is no memory effect on the Lithium ion
batteries, which means that you do not need to
discharge them completely before recharging,
this is called "trickle charging". For approximate
charging times see Self Help on our Service and
Support website at www.8fujitsu.com. Once
there click on
Self Help Center . Using the
pull-down menus select C Series, then
select
Specifications, then your unit.

You may not be able to hear the audio
alarms if the volume control is set too
low or is turned off by either hardware
or software but you will still be able to
see the Battery Level indicator flash.
Low Battery State
When the battery is running low, your note-
book beeps about every 15 seconds and the
Battery Level indicator flashes. If you do not
respond to the low battery alarm, the battery
will continue to discharge until it is too low to
operate. When this happens there will be a
multiple beep alarm, the Battery Level indicator
will show dead battery, and your notebook will
go into Suspend mode to try and protect your
data as long as possible. Your power manage-
ment settings do not effect what happens at the
dead battery alarm level. Your notebook will go
to Suspend mode.
(Figure 3-2 on page 21.)
When the low battery alarm occurs, you need
to save all your active data and put your note-
book into Suspend mode until you can provide
a new power source. You should provide this
power as soon as possible. The new power
source can be a charged battery or a power
adapter, either AC or auto/airline.
C A U T I O N
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 button, or remove all
power sources, battery, AC adapter or
auto/airline adapter, while your note-
book is in Suspend mode any data which
has not been saved to the hard drive
will be lost.
