An open industry specification that enables software designers to integrate features for power management throughout a computer system, including the hardware, operating system, and application software.
Advanced Configuration and Power Interface (ACPI) is supported by Microsoft Windows 2000 and enables the operating system to handle all the power-management resources for computer subsystems and peripherals.
ACPI works with subsystems and peripherals for a wide range of mobile, desktop, and server platforms. ACPI is also the foundation for the OnNow industry initiative that enables computers to start at the touch of the keyboard.
ACPI support can be enabled for Windows 98 by running Setup using the following command-line switch:
setup /p j
Running Setup in this mode adds the ACPIOption string value with a value data of 1 to the Windows 98 registry and causes hardware devices to be queried for ACPI support during setup. Note that Windows 98 does not support all ACPI features, for example Passive Cooling Mode.
