First off I am technically challenged so please be patient. I turned the lights off on my controller on my laptop early this morning to clean them. When I try to slide the switch to turn them back on it won't move. All the other switches are on but I'm afraid to test them. Also, the whole switch area has diagonal faint lines across it. Has anyone experienced this problem before? Too add one more bit of information I just replaced my laptop with a new one although all the data was switched over. Is there something else I need to do? Thanks for any help.
