Power Management; Power/Suspend/Resume Button; Standby (Sleep) Mode - Fujitsu LIFEBOOK S762 User Manual

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 Standby (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
Standby (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
Standby mode. If the indicator is not visible, the power is off or your notebook is in Hibernation mode.

Standby (Sleep) Mode

Sleep mode in Windows saves the contents of your system memory during periods of inactivity by maintaining power
to critical parts. This mode turns off the CPU, display, hard drive, and all other internal components except those
necessary to maintain system memory and for restarting.
Your notebook can be put in sleep mode by:
• Pressing the Power/Suspend/Resume button when your system is turned on.
• Selecting "Sleep" after clicking [Start] then clicking the small arrow at the bottom right of the window.
• Timing out from lack of activity.
