10.3: Understanding PowerBook screen dimming timing System
I've just upgraded to Panther, sorry if this is also true in 10.2.x. I saw this on my TiBook 500Mhz.

In the Energy Saver preferences, if you set your display to sleep in 1 hour (for example), it will sleep in 1 hour ... but it will dim in 30 minutes! As far as I can tell, you are stuck with the dimming time always being 50% of the sleep time. The only way to see this is to see the pop up info over the Display sleep slider -- hover over the slider, and you'll see "Dim 30 minutes. Sleep 1 hour."

Since the dimming interval is fixed, if you want to maximize your battery life by dimming the screen quickly, you'll also have to set a reasonably short time for putting the display to sleep.

you can set dimming directly using:
pmset -g
retrieves the current values, and
sudo pmset -c dim 0
claims to turn off dimming. I haven't had luck turning dimming off, but at least you can set it to something other than the default 50%. Of course
man pmset
for all the details.

'dim' in pmset refers to 'Display Sleep' in Energy Saver.

The 'Dimming' in Energy Saver refers to the slight reduction in screen brightness that occurs on laptops and seems to be fixed at 50% of Sleep (or dim in pmset).
