What I need is to extend the delay before the display dims. I will often read a page full of text and the screen will dim, and I have to touch the trackpad. It gets annoying when trying to take notes or do homework.
This is for a 13" 2008 MacBook Aluminum.
I am aware of the
pmset halfdim switch. That switch corresponds to the automatically reduce the brightness of the display before sleep in the Energy Saver preferences pane. But it's not what I need. I do like the feature, but I'd just like to extend it 15-20 seconds.
