Power Management

Power management is implemented at several levels, including:

•    Software support through Advanced Configuration and Power Interface (ACPI)

•    Hardware support:

      –  Suspend to RAM (Instantly Available PC technology)

      –  Power connectors

      –  Fan connectors

      –  Resume on Ring

      –  Wake from USB

      –  Wake from PS/2 keyboard/mouse

      –  PME# wakeup support

Software Support through ACPI

The  Advance  Configuration  and  Power  Interface  (ACPI)  –  aware  operating  system  can  place  the 
system into a state where the hard drives spin down, the system fans stop, and all processing is 
halted. In this state, the power supply is still on and the processors still dissipate some power, so 
the power supply fan and processor fans are still running.

Under ACPI, the operating system directs all system and device power state transitions. The operating 
system puts devices in and out of low-power states Based on user preferences and knowledge of 
how devices are being used by applications. Devices that are not being used can be turned off. The 
operating system uses information from applications and user settings to put the system as a whole 
into a low-power state.

ACPI features include:

•    Plug and Play (including bus and device enumeration).

•    Power management control of individual devices, add-in boards (some add-in boards may 

      require an ACPI-aware driver), video displays, and hard disk drives.

•    Methods for achieving less than 15-watt system operation in the power-on/standby 

      sleeping state.

•    A soft-off feature that enables the operating system to power-off the computer.

•    Support for multiple wake-up events.

•    Support for a front panel power and sleep mode switch.
