What is Advanced Configuration And Power Interface (ACPI)?

What does ACPI stand for?

Advanced Configuration and Power Interface (ACPI) is an enterprise specification intended for the efficient management of electricity intake in Cell and Computing Device Computer Systems. ACPI describes the manner in which a Computer’s fashionable enter/Output sySTEM, Peripheral gadgets and operating gadget (OS) correspond regarding energy consumption. ACPI’s key aim is to consolidate, examine and enhance the present energy and configuration standards supposed for Hardware devices.

Launched December 1996, ACPI specifies Platform-unbiased interfaces supposed for configuration, hardware Discovery, Monitoring and energy management. This standard become iNitially designed by way of Intel, Toshiba and Microsoft and later observed through Phoenix and HP.

What Does Advanced Configuration And Power Interface Mean?

ACPI offers a crossover from in advance standards to hardware this is absolutely ACPI-compliant. Geared in the direction of substituting the Plug and Play (PnP) primary enter/output system (BiOS) specification, Multiprocessor specification and advanced Power Control, the ACPI wellknown provides electricity to running device energy management (OSPM), in evaLuation to earlier BIOS critical structures that primarily rely on platForm unique Firmware to determine electricity control and configuration coverage.

ACPI consists of diverse associated Components for Software and hardware Programming, as well as a uNiFied trendy for electricity/device interplay and Bus configuration. With ACPI, the subsequent Functions are feasible, presuming they are supported with the aid of the OS:

• Users can specify a time in which a tool, which include a display screen, is turned off or on.
• Users of a notebook pc can specify low level power consumption at some point of a low-Battery caution, allowing required Packages to run at the same time as making less essential packages inactive.
• OSs can reduce the Clock Speed if the packages do now not require full Processor cLock speed.
• OSs can lower Peripheral Device and Motherboard electricity intake via the inactivation of gadgets, while not required.
• Computers can go into Standby Mode if the machine is not in use. However, the Modem power remains on in order that incoming mails/faxes may be acquired.
