Power management reduces the power consumption of certain
components of the computer such as the system power supply, processor,
hard disk drives, and some monitors.
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.
The Automatic Power-On features within the Power Management menu
allow you to enable and disable features that turn on the computer
automatically.
• Serial Port A Ring Detect: With this feature set to Enabled and an
external modem connected to serial port (COM1), the computer will
turn on automatically when a ring is detected on the modem.
• PCI Modem Ring Detect: With this feature set to Enabled, the computer
will turn on automatically when a ring is detected on the internal
modem.
• PCI Wake Up: This feature allows PCI cards that support this capability
to wake the system.
• Wake Up on Alarm: You can specify a date and time at which the
computer will be turned on automatically. This can be either a single
event or a daily event.
