I see 2 check boxes:

	Reduce backlight brightness
	Dim display when idle

I have both of them set.
I also have the slider set to 20 minutes
	(Put display to sleep when inactive for)

Also, my laptop has a couple of Fn buttons to control screen brightness.
I looked at the ASUS scripts that came with my system, and none of them
seem to control screen brightness, so I assume that they control the
screen brightness directly?

I too notice that the minute I go on battery, the whole screen dims.

I see slightly different behaviour.  When I unplug from power, the
screen dims.  I then use the buttons to return the screen brightness to
where I want it.  Then (some time later) while using the touchpad (mouse
and clicks) the screen all of a sudden dims again, even more.  If I then
use the buttons to return it to where I want, just a short time after
that the screen dims *again*.  Makes me wonder what "idle" is looking at
for activity, since power management has been overridden manually, yet
insists on asserting itself again, and again, and again, ....

Sorry, not helping, just commiserating....
