indicator LED
turns red. If connect the
AC adapter to your notebook immediately to
recharge the battery.

in lost of data you are currently working
on. When the battery runs low, connect
the AC adapter to your notebook as
soon as an external power source is
available or immediately save the data
you are working on, exit all applications
Accessing data on the storage drive
consumes a lot of power. Therefore
when the battery is weak, connect an
AC adapter to the notebook before
accessing data on the storage drive.
If a battery is weak and there is no
system activity, the notebook may
go into standby (i.e. suspend) mode.
However, if there is system activity, the
notebook will go into standby mode
only after the system activity has
completed its processing.
The notebook will go into standby
mode when the indicator reaches
3%. This is the default setting of the
notebook.

Using Your LIFEBOOK
POWER MANAGEMENT
Your Fujitsu LIFEBOOK has many options and
features for conserving battery power. Some
of these features are automatic and need no
user intervention, such as those for the internal
modem. However, others depend on the
parameters you set to best suit your operating
conditions, such as those for the display
brightness. Internal power managements for
your notebook may be controlled from settings
made in your operating system, pre-bundled
power management application, or from
settings made in BIOS setup utility.
Besides the options available for conserving
battery power, there are also some things that
you can do to prevent your battery from running
down as quickly. For example you can create
as appropriate power saving profile, put your
notebook into Suspend mode when it is not
performing as operation, and you can limit the
use of high power devices. As with all mobile,
battery power computers, there is a trade-off
between performance and power savings.
Power/Suspend/Resume Button
When you LIFEBOOK is active, the Power/
Suspend/Resume button can be used to
manually out your notebook into Suspend
mode. Push the Power/Suspend/Resume
button when your notebook is active, but not
actively accessing anything, and immediately
release the button. You will hear two short
beeps* and your system will enter Suspend
mode.
If your LIFEBOOK is suspended, pushing the
Power/Suspend/Resume button returns your
notebook to active operation. You can tell
whether the system is Suspended by looking at
the Power indicator. If the indicator visible and
notebook is in Suspend mode. If the indicator is
in Hibernation mode.(See Hibernation Feature)
* Only applicable for some models
Using Your LIFEBOOK
Suspend Mode
Suspend or Standby mode in Windows saves
the contents of your notebook's system
m e m o r y d u r i n g p e r i o d s o f i n a c t i v i t y b y
maintaining power to critical parts. This mode
drive, and all of the other internal components
except those necessary to maintain system
memory and allow for restarting. Your notebook
can be put in Suspend mode by:
button when your system is turned on.
Down menu.
Timing out from lack of activity.
Battery warning condition.
Your notebook's system memory typically
working, open application information, and any
other data required to support operation from
Suspend mode, your notebook will return to the
Suspend/Resume button to resume operation,
and there must be as adequate power source
available, or your notebook will not resume.
If you are running your LIFEBOOK
on battery power, be aware that the
battery continues to discharge while
your notebook is in Suspend mode,
though not as fast as when fully
operational.
The main advantage of using the
Hibernation (Save-to-Disk) function is
that power is not required to maintain
your data. This is particularly important
if you will be leaving your LIFEBOOK
notebook in a suspended state for
a p r o l o n g e d p e r i o d o f t i m e . T h e
drawback of using Hibernation mode
is that it lengthens the power down
and power up sequences and resets
peripheral devices.
