ok its not a big deal per say but on a dell studio xps it has all the like "touch screen buttons" above the keyboard to pause/play, skip, ff, rwnd, and change volume well when my laptop dies all together them keys black out when i plug it back in and i can never figure out how to turn them back on. its really annoying to close down the video just to adjust the main volume or pause and so on just a inconvenience its quicker just to be able to tap the button but the button isn't there now how do i get them to show up again.
