POWER MANAGEMENT
Your Fujitsu LifeBook notebook 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 management 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
an appropriate power saving profile, put your
notebook into Suspend mode when it is not
performing an operation, and you can limit the
use of high power devices. As with all mobile,
battery powered computers, there is a trade-off
between performance and power savings.
POWER/SUSPEND/RESUME BUTTON
When your LifeBook notebook is active, the
Power/Suspend/Resume button can be used
to manually put 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 is visible and not
flashing, your notebook is fully operational. If the
indicator is visible and flashing, your notebook is
in Suspend mode. If the indicator is not visible,
the power is off or your notebook is in Hibernation
mode. (See Hibernation Feature)

Getting to Know Your LifeBook
SUSPEND MODE
Suspend or Standby mode in Windows saves
the contents of your LifeBook notebook's
system memory during periods of inactivity by
maintaining power to critical parts. This mode
will turn off the CPU, the display, the hard 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:
• Pressing the Power/Suspend/Resume button
when your system is turned on.
• Selecting Standby from the Windows Shut
Down menu.
• Timing out from lack of activity.
• Allowing the battery to reach the Dead Battery
Warning condition.
Your notebook's system memory typically
stores the file on which you are working, open
application information, and any other data
required to support operations in progress. When
you resume operation from Suspend mode, your
notebook will return to the point where it left
off. You must use the Power/Suspend/Resume
button to resume operation, and there must be
an adequate power source available, or your
notebook will not resume.
If you are running your LifeBook notebook
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.
Disabling the Power/Suspend/Resume
button prevents it from being used to put
your LifeBook notebook in Suspend or
Hibernation (Save-to-Disk) mode. The
resume function of the button cannot be
disabled.
