My laptop home button won't work. What do I do?

My laptop home button -keyboard or onscreen- won't work. It continuously makes a little dark bit go over the button onscreen, but nothing happens. What should I do to fix this?

Hello... Typically there will be a "Utility" pre-installed in your APPS... to program and configure your "special" or "hot keys" for it.
