ACPI (Advanced Configuration Power Interface)
A technology that allows the operating system controls the amount of electrical power used by each device installed on the computer. Usually provided so that these devices save energy. ACPI is an interface and is intended for software and hardware.Operating system that is able to perform configuration and power management of the system, often referred to as the Operating System-directed configuration and Power Management (OSPM). Joint ACPI OSPM performs power management with the concept that a system will save energy by changing a piece of equipment that is currently unused by the system to a state that uses less power (power lowed state). This concept also applies to the entire system, making the whole system is in a condition that uses less power (sleeping state). Some of the sleeping state that are available include:S1 Sleeping StateA sleeping state that when awakened will have a low delay rate. In the S1 sleeping state there is no system context is lost, not on the processor and chipset.S2 Sleeping StatA sleeping state that when awakened will have a low level of delays as well as the S1 sleeping state, only the S2 sleeping state is the processor context and system cache context is lost. The operating system will be responsible for maintaining the context of the processor and cache it.S3 Sleeping StateA sleeping state that when awakened will have a low level of delays as well, but all systems except in the context of main memory will be lost. S3 sleeping state is often referred to suspend to RAM.S4 Sleeping StateA sleeping state that when awakened will have a high level of delay (the highest supported by the ACPI) and has the most power usage levels are low (the lowest supported by ACPI). In the S4 sleeping state is considered to be all the hardware is turned off, it's just that his context is maintained. S4 sleeping state is often referred to as suspend to disk.S5 Sleeping StateS5 soft off it has in common with the S4 sleeping state, it's just the operating system does not store any context
