Power Management Your LifeBook notebook has many options and features for conserving battery power. Some of these features are automatic and need no user intervention. 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. PLEASE NOTE THAT "STANDBY MODE" IN WINDOWS XP IS KNOWN AS "SLEEP MODE" IN WINDOWS VISTA. THE TWO TERMS ARE INTERCHANGEABLE. FOR PURPOSES OF THIS DOCUMENT, "SLEEP MODE" WILL BE USED. 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 Sleep 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 notebook is active, the Power/Suspend/Resume button can be used to manually put the notebook into Sleep mode. Push the Power/Suspend/Resume button when the notebook is active, but not actively accessing anything, and immediately release the button. If your notebook 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 Sleep mode. If the indicator is not visible, the power is off or your notebook is in Hibernation mode. See "Hibernation (Save-to-Disk) Feature" on page 59. 57 - Power Management

Power Management
Your LifeBook notebook has many options and features for conserving battery power. Some of these
features are automatic and need no user intervention. 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 Sleep 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 notebook is active, the Power/Suspend/Resume button can be used to manually put the
notebook into Sleep mode. Push the Power/Suspend/Resume button when the notebook is active, but
not actively accessing anything, and immediately release the button.
If your notebook 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 Sleep mode. If the indicator is not visible, the power is off or your
notebook is in Hibernation mode.
