Advanced Configuration and Power Interface (ACPI) is an industry specification intended for the efficient management of power consumption in mobile and desktop computers. ACPI describes the way in which a computer’s standard input/output system, peripheral devices and operating system (OS) correspond regarding power consumption.

ACPI, or Advanced Configuration and Power Interface, is an open industry specification that enables software designers to integrate features for power management throughout a computer system, including the hardware, operating system, and application software.

Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.

The Advanced Configuration and Power Interface (ACPI) specification was developed to establish industry common interfaces enabling robust operating system (OS)-directed motherboard device configuration and power management of both devices and entire systems.
