Since it is shipped with Win8, I think the following patch should take care of it: [PATCH] ACPI / video: Use native backlight control interface by default http://www.spinics.net/lists/linux-acpi/msg47755.html Last time Daniel seems to agree to merge it for test purpose, but I didn't see it get merged somewhere yet.
