In addition to providing operating-system power management, ACPI offers a
generic system event mechanism for Plug and Play and an operating-system-
independent interface for configuration control. Plug-and-Play BIOS data structures
are leveraged, while the implementation is processor-architecture-independent and
compatible with both Windows 2000, Windows XP, and Windows 2003 Server
Operating Systems.
1.1.2.1 Suspend-State Indicator
When the CPU enters a suspend state, the
Power
LED will start blinking to indicate
that the CPU is in suspend mode. Pressing any key on the keyboard will awaken the
CPU, at which time the power LED will stop blinking and remain on.
1.1.2.2 Main Switch Override
ATX 2.01 (or higher)-compliant power supply only. If enabled in the system setup,

modem card and the corresponding setting is enabled in the system BIOS settings.
1.1.2.4 Wake-On-LAN (WOL)
ATX 2.01-compliant (or higher) power supply only . The
Wake-On-LAN
utility
