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 profi le, 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 fl ashing, 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)

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 fi le 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.
