Also I can confirm there are _CPC entries in the ACPI tables. acpidump > acpidump.out acpixtract -a acpidump.out iasl *.dat grep -i cpc *.dsl ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control ssdt7.dsl: Name (_CPC, Package (0x17) // _CPC: Continuous Performan= ce Control Any ideas why the driver cannot find them?
