What Is The Meaning Of ACPI?
Meaning Of ACPI In English,
The term ACPI is an acronym that stands for “Advanced Configuration and Power Interface”. In a computer, the ACPI most commonly facilitates an open standard that operating systems can utilize to discover and configure computer hardware components, to execute power management.
The ACPI was first released in December 1996. The ACPI’s main aims are to replace Advanced Power Management (APM), the Multiprocessor Specification, and the Plug and Play BIOS (PnP) Specifications.
Interiorly, ACPI publishes the available parts and their functions to the operating system Kernel using command lists given through the system firmware (Unified Extensible Firmware Interface [UEFI] or BIOS), which the kernel parses.
After that, ACPI executes the desired operations written in ACPI Machine Language using an embedded minimal virtual machine. It would be interesting to know that, Microsoft’s Windows 98 was the first operating system to implement ACPI, but its implementation was somewhat foolish or incomplete, while some of the difficulties connected with it were produced by the first-generation ACPI hardware.
Windows 98 first edition disabled ACP by default except on a whitelist of systems. The other various operating system comprises of later sorts of Windows, eComStation, FreeBSD, NetBSD, HP-UX, OpenVMS, and PC versions of Solaris, have at minimum some support for ACPI.
What Is ACPI Settings In BIOS?
ACPI (Advanced Configuration and Power Interface) gives the BIOS and operating system control over various devices’ power and modes of operation, as shown in Figure 4.28. With ACPI, the user can control how the power switch operates and when power to specific devices, such as the hard drive and monitor, is lowered.
What Are ACPI Devices?
ACPI devices include low-level system devices such as batteries, thermal zones, and other devices defined in a system’s ACPI namespace. An ACPI namespace is a hierarchical namespace that an ACPI BIOS uses to reference objects.
