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. See “Hibernation (Save-to-Disk) Feature” on page 55.
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.
