Comment 2 for bug 296663

thank for you report but to be able to fix the hotkeys on your laptop we need three things:

   1. What the key *should* do.
   2. What keycode (magic number) the key produces on your laptop.
   3. How to identify your laptop by the manufacturer and model.

You can see the following documentation to know how to do that:

Marked as incomplete until we have more information.
