58 - Power Management
Power Management
Your 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 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.
Suspend/Resume Button
When your notebook is active, the Suspend/Resume button can be used to manually put the notebook into
Sleep mode. Push the button when the notebook is active, but not actively accessing anything, and
immediately release the button. You will hear two short beeps and the system will enter Sleep mode.
If your notebook is suspended, pushing the 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 Feature)
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 Suspend/Resume button when your system is turned on.
