Power Management Setup
ACPI (Advanced Configuration and Power Interface) is an open industry standard that defines
power and configuration 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 specification must be
supported by the OS (for example, Windows XP or Windows Vista).
ACPI defines four sleeping states below, 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
)
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 configuration 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.
