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

Power Management

Your 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 the 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
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 saves your notebook's system memory contents 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 LIFEBOOK notebook can be put in Sleep mode by:
• Pressing the Power/Suspend/Resume button when your system is turned on.
• Clicking the power icon on the lock menu.
• Selecting Sleep from the [Settings]->[Power] menu.
