The last error message is definitely caused by a bug in the DSDT, but that that shouldn't prevent the values from showing up (I assume you tried on a wide terminal). Can you send me the following informations: 1. Output of cat /dev/wmistat (cat /dev/wmistat >/tmp/wmistat.out) 2. Output of cat /dev/hpcmi with cmi_detail set to 7 (sysctl dev.acpi_hp.0.cmi_detail=7; cat /dev/hpcmi >/tmp/hpcmi.out) 3. Your DSDT (acpidump -dt > /tmp/my_computer.asl) thanks Michael
