4.7.2 POWER MANAGEMENT

This system provides baseline hardware support of ACPI- and APM-compliant firmware and
software. Key power-consuming components (processor, chipset, I/O controller, and fan) can be
placed into a reduced power mode either automatically or by user control. The system can then be
brought back up (“wake-up”) by events defined by the ACPI specification. The ACPI wake-up
events supported by this system are listed as follows:

4.7.3 SYSTEM STATUS
