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)
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 respon-
sible 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
are lost in this state. Hardware maintains memory
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 plat-
form 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.
