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?

A:

Maybe it doesn't like you anymore.

 

Reset the PRAM via the instructions on this page.  http://support.apple.com/kb/HT1379

 

Reset SMC via the instructions on this page.  http://support.apple.com/kb/ht3964

 

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.
