How to Enable Acpi in BIOSby TS Jordan ; Updated February 10, 2017
ACPI (Advanced Configuration and Power Interface) is a power setting in your computer's Binary Input Output System (BIOS) which is necessary if you are using any ACPI-compliant devices on your computer system. Enable it quickly through the power control features of your BIOS. This procedure generally takes no longer than five minutes.
Restart the computer.
Press the key for entering BIOS that is indicated in the system's startup messages. On most computers this is one of the "F" keys, but two other common keys are the "Esc" or "Del" keys.
Highlight the "Power Management" option and press "Enter."
Highlight the "ACPI" setting, press "Enter," and select "Enable."
