Power Management; Power/Suspend/Resume Button; Standby Mode - Fujitsu LifeBook M2011 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 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 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 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. (See Hibernation Feature)

Standby Mode

Standby 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 Standby mode by:
• Pressing the Power/Suspend/Resume button when your system is turned on.
• Selecting Sleep from the Shut down menu (click 5the small arrow to the right of the [Shut down]
button).
