Power
ACPI(AdvancedCongurationandPowerInterface)isanopenindustrystandardinterfaces
enablingOS-directedconguration,powermanagement,andthermalmanagementof
mobile,desktop,andserverplatforms.It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.
►ACPISleepState
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
