It is meant to query the "set of ACPI-related interfaces, = behaviors, or features that the operating system supports" (from ACPI = specification.)

The machine came with Windows 7. My guess is that they have another = piece of software that does the same as the ASUS010 interface (LCD = brightness control / disabling enabling devices / etc.) but for Windows = 7. -- Rui Paulo
