What Is Acpi Flash BIOS?

By Kevin Caron

Advanced Configuration and Power Interface, or ACPI, is a set of standard computer configuration, power management and thermal management specifications developed by a number of computer manufacturers. Flashing ACPI BIOS is a term for applying an update to a computer's ACPI.


ACPI was developed by the Hewlett-Packard, Intel, Microsoft, Phoenix and Toshiba companies to provide manufacturers with a standard system of power and thermal management as well as a standard configuration interface. This standard allows new technologies to be developed that will work across ACPI computers, regardless of the manufacturer.


BIOS is an acronym that stands for basic input/output system. It is the program that controls the start-up of your computer and allows your computer hardware to communicate with the operating system. All computers with ACPI BIOS installed will perform BIOS functions in the same way.

Flashing ACPI BIOS is the method of applying an update to your computer's ACPI BIOS. This completely overwrites the BIOS on your machine, replacing it with an updated version; as such, it is a risky process that should only be performed if absolutely necessary for your computer to support a needed application.
