Advanced configuration and power interface or ACPI advanced configuration and power industry is an open industry specification that enables software designers to integrate features for power management for other computer systems including the hardware operating system and application software. ACPI is supported by the Microsoft Windows family and enables the operating system to handle all the power management and resources for computer subsystems and performs ACPI at work with subsystems and peripherals for a wide range of mobile desktop and server platforms. It is also the foundation for the industry initiative that enables computers to start at the top of the keyboard. Advanced configuration and power interface is in response to global concerns about energy conservation and environmental control. ACPI is replaced with all technology and more recently. Advanced technology based on the collaborative effort of Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. ACPI moves away from power management that simply times out during activity to a more sophisticated demand based power management. It collects information about power consumption. Internet connection systems the operating system then distributes power to different computer components on as needed basis with a CGI. The computer can power itself down to a deep sleep state but still be capable of responding to an incoming phone call or a time backup procedure. Another feature is the hibernation mode before the computer goes into a deep sleep or hibernation the contents of RAM are written to an image file saved on the hard drive. When the computer is turned back on, the image file is reloaded eliminating the need to reboot the system and open applications.
