Advanced Configuration and Power Interface

The full form of ACPI is the Advanced Configuration and Power Interface. It provides an open standard with operating systems that can be used to discover and configure computer hardware components to perform for management by putting unused components to sleep. It was first released in December 1996 with the aim to replace advanced power management, the multiprocessor specification, and the plug and play bios. It brings power management under the control of the operating system as opposed to the previous bios centric system that relied on platform-specific firmware to determine power management and configuration policies.
