Commenting out the if on SSHU does indeed make the thermal zone show the same temp as the third temp value from mbmon. Where should Store(SSHU, Debug) print? I don't see anything on the console. Do I need to compile acpi with ACPI_DEBUG? (Just curios - I don't think I will bother since it now works.) iasl however complained so I had to force with -f: Intel ACPI Component Architecture ASL Optimizing Compiler / AML Disassembler version 20041119 [Oct 21 2006] Copyright (C) 2000 - 2004 Intel Corporation Supports ACPI Specification Revision 2.0c a8n-e-hack.asl 461: Method (\_WAK, 1, NotSerialized) Warning 2026 - ^ Reserved method must return a value (_WA K) a8n-e-hack.asl 2779: Name (_HID, "_NVRAIDBUS") Error 1068 - String must be entirely alphanumeric ^ (_NVRAIDBUS) a8n-e-hack.asl 3026: Method (RVLT, 1, NotSerialized) Warning 2019 - ^ Not all control paths return a value (RVLT) a8n-e-hack.asl 3146: Method (RTMP, 1, NotSerialized) Warning 2019 - ^ Not all control paths return a value (RTMP) a8n-e-hack.asl 3341: Method (OCOP, 1, NotSerialized) Warning 2019 - ^ Not all control paths return a value (OCOP) a8n-e-hack.asl 4212: Method (GCQV, 1, NotSerialized) Warning 2019 - ^ Not all control paths return a value (GCQV) ASL Input: a8n-e-hack.asl - 7252 lines, 213903 bytes, 3003 keywords Compilation complete. 1 Errors, 5 Warnings, 0 Remarks, 850 Optimizations Regards, Bengt
