Power management
Power management reduces the power consumption of certain components of
the computer such as the system power supply, processor, hard disk drives,
USB keyboard or mouse, and some monitors.
Automatic configuration and power interface (ACPI) BIOS
Being an ACPI BIOS system, the operating system is allowed to control the
power management features of the computer and the setting for Advanced
Power Management (APM) BIOS mode is ignored. Not all operating systems
support ACPI BIOS mode.
Automatic power-on features
The automatic power-on features allow you to enable and disable features that
turn on the home center automatically.
• After Power Failure: You can specify in BIOS to enable or disable the home
center to resume from previous power state after a power failure occurs.
• On LAN Wake Up: The home center includes a Lights Out client software
that allows the LAN adapter card to wake the home center. See the User
Guide for more information.
