Power Management Setup

ACPI (Advanced Conguration and Power Interface) is an open industry standard that denes

power and conguration management interfaces between an operating system and the BIOS.

In other words, it is a standard that describes how computer components work together

to manage system hardware. In order to use this function the ACPI specication must be

supported by the OS (for example, Windows 2000 or Windows XP).

ACPI denes ve sleeping states, they are :

S1 - The S1 sleeping state is a low wake latency sleeping state. In this state, no system

context is lost (CPU or chip set) and hardware maintains all system context. (also called

Power On Suspend)

S2 - The S2 sleeping state is a low wake latency sleeping state. This state is similar to

the S1 sleeping state except that the CPU and system cache context is lost (the OS

is responsible for maintaining the caches and CPU context). Control starts from the

processor’s reset vector after the wake event.

S3 - The S3 sleeping state is a low wake latency sleeping state where all system context is lost

except system memory. CPU, cache, and chip set context are lost in this state. Hardware

maintains memory context and restores some CPU and L2 conguration context. Control

starts from the processor’s reset vector after the wake event. (also called Suspend to

RAM)

S4 - The S4 sleeping state is the lowest power, longest wake latency sleeping state supported

by ACPI. In order to reduce power to a minimum, it is assumed that the hardware platform

has powered off all devices. Platform context is maintained. (also called Suspend to

Disk)

S5 - The S5 state is similar to the S4 state except that the OS does not save any context. The

system is in the “soft” off state and requires a complete boot when it wakes. Software

uses a different state value to distinguish between the S5 state and the S4 state to allow

for initial boot operations within the BIOS to distinguish whether or not the boot is going to

wake from a saved memory image.
