ACPI (Advanced Configuration and Power Interface) is an open industry standard interfaces
enabling OS-directed configuration, power management, and thermal management of mobile,
desktop, and server platforms. It defines five 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
)
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.
► ACPI Suspend Type
This item is used to set the energy saving mode of the ACPI function. When you select “S1
(POS)” mode, the power is always on and computer can be resumed at any time. When
you select “S3 (STR)” mode, the power will be down after a period of time. The status of the
computer before it entering STR will be saved in memory, and the computer can quickly return
to previous state when the STR function wakes.
