IPCA Function

ACPI Suspend Type
This item specifies the power saving modes for ACPI function. Options are:
S1 (POS)
S3 (STR)
S1 & S3
The S1 sleep mode is a low power state. In this state, no
system context (CPU or chipset) is lost and hardware
maintains all system context.
The S3 sleep mode is a power-down state in which power
is supplied only to essential components such as main
memory and wake-capable devices and all system con-
text is saved to main memory. The information stored in
memory will be used to restore the PC to the previous
state when an "wake up" event occurs.
Both S1 & S3 modes will be adopted.
