I could not get anything but -EINVAL from IBM > ACPI driver :-(. thinkpad-acpi will regard 128 and -128 as invalid sensors, because that's how they are used in some BIOSes (and ECs). We used to bother only with -128, but Lenovo did something wierd in one of the EC firmwares and I had to add +128 too. That masks the "help, I am melting" reading. I have noted that in my TODO, let's see if I can make that into a quirk so that you won't get -EINVAL anymore. -- "One disk to rule them all, One disk to find them.
