Sensors shows a reading for "POWER > Temperature" which is 26C; this reading is missing from the BIOS > despite the manual saying it should be shown.

Note that the driver retrieves the label strings directly from the system firmware (ACPI), it does not make them up; those labels are used by Asus windows utility so I'd trust them. Can you send me a dump of your DSDT table (/sys/firmware/acpi/tables/DSDT)? > Also can anyone tell me what these temperature sensors actually correspond > to? I'd like to know what MB, PCH and POWER Temperature actually correspond to. Sometimes the manual indicates where the temperature probes are localed. PCH is the southbridge in Core i7 mobos. Power might refer to the regulators near the CPU.
