I enabled power daemon and set it between all the modes, the fan slows down a little depending on the selected mode, but usage remains the same for the acpi task. I updated the bios to see if it made a difference as well, but no change. I’ve chalked it up to something with acpi and this version of the kernel in FreeBSD that’s beyond my ability to figure out and rolled back to 2.3.4.
Thanks for the suggestion.
