Q: I tried this but it still won't work. When I try to brighten it, a box with a dash pops up.
I tried what this said to do, but when I try to turn it out by using the brightening button, a box with a dash pops up and won't let me do anything. What does this mean?

Maybe it doesn't like you anymore.
Reset the PRAM via the instructions on this page. http://support.apple.com/kb/HT1379

The SMC reset may not be necessary, so do the PRAM first. If that fixes it, leave it at that and don't do the SMC reset.
