ACPI

ACPI, or Advanced Configuration and Power Interface, is a standard that helps your computer manage its hardware and power usage efficiently. It allows the operating system to control things like turning off unused devices, managing power for different components, and controlling system states (like sleep or hibernate). This makes your computer more energy-efficient, extends battery life on laptops, and improves overall system stability by providing a coordinated way for hardware and software to communicate about power and device management.
