2.4.15 AXIOMTEK ACPI Connector (CN4)

Advanced Configuration and Power Interface (ACPI) defines a flexible

and extensible interface that allows system designers to select

appropriate cost/feature trade-offs for power management. The

interface enables and supports reliable power management through

improved hardware and operating system coordination. The

specification enables new power management technology to evolve

independently in operating systems and hardware while ensuring that

they continue to work together.

CN4 is a 6-pin header connector that provides ACPI interface.
