How can I disable ACPI and what are the advantages and disadvantages of enabling ACPI?
First off, I think a little introduction is needed as to what ACPI is. ACPI (Advanced Configuration and Power Interface) is a power management specification that allows the operating system to control the amount of power distributed to the computer’s devices. Devices not in use can be turned off, reducing unnecessary power expenditure. ACPI defines a new interface to the system board, and enables the OnNow design initiative for instantly available PCs. ACPI is actually a substitute for APM (Advanced Power Management) at the hardware-software level. Unlike APM, which deals with the power management directly through the BIOS, ACPI, instead exposes the tables present in the various installed hardware devices in the system to the operating system. ACPI, in effect, hands off control of power management to the operating system. ACPI is merely a standard implemented by hardware vendors to provide standardized interfaces that are ACPI compliant. In this manor, much of the work done for power m
