(Some BIOS may allow to select the profile preference also) You can use the hw.acpi.cpu.economy_speed and .performance_speed sysctl to select the amount of CPU throttling. The hw.acpi.cpu.current_speed contains the current speed :) and .max_speed contains the highest possible value. Select the profile by unplugging/plugging-in your AC connector *g >=20 > The second thing that I cannot seem to figure out is how to change the sc= reen > brightness.
