Power Management; Power/Suspend/Resume Button; Sleep Mode - Fujitsu LIFEBOOK AH532 Guide D'utilisation

Power Management

Your notebook has many options and features for conserving battery power. Some are automatic and need no user
intervention. However, others depend on parameters you set to best suit your operating conditions, such as those for
the display brightness. Internal power management can be controlled by settings made in the operating system,
power management application, or 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.

Sleep mode. Push the Power/Suspend/Resume button when the notebook is active, but not actively accessing
anything, and immediately release the button. Note that if you press the button continuously for four seconds or
longer, your notebook will shut down.
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
