Power Management; Suspend/Resume Button; Suspend Mode - Fujitsu P2110 Manual

SECTION 2

4. 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, prebundled 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.

Suspend/Resume Button

When your LifeBook notebook is active, the Suspend/ Resume button can be used to manually put
your notebook into Suspend mode. Push the 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 notebook is suspended, pushing the Suspend/Resume button will return your notebook
to active operation. You can tell whether or not your system is in Suspend mode by looking at the
Power indicator. If the indicator is visible and not flashing, your notebook is fully operational. If the
indicator is both visible and flashing, your notebook is in Suspend mode. If the indicator is not visible
at all, the power is off or your notebook is in Hibernation mode.

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 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 LifeBook notebook's system memory typically stores the file(s) on which you are working, open
application (s) information, and any other data required to support the operation(s) in progress. When
you resume operation from Suspend mode, your notebook will return to the point where it left off. You
must use the Suspend/Resume button to resume operation, and there must be an adequate power
source available, or your notebook will not resume.
