ACPI Features
Advanced Configuration and Power Interface (ACPI) defines a flexible and abstract
hardware interface that provides a standard method of integrating power manage-
ment features throughout the system. This includes the hardware, the operating sys-
tem, and the application software. As a result, the system can automatically turn
peripherals (CD-ROMs, NICs, storage drives, and printers, for example) on or off.
This includes any consumer devices that may be connected to the system (VCRs,
TVs, telephones, and stereo systems, for example).
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 lever-
aged, while the implementation is processor architecture-independent and compati-
ble with both Windows 7, Windows Vista, and Windows 2008 Operating Systems.
1.4.5
Slow Blinking LED for 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.
