When I press fn+left/right arrow keys the brightness of the screen doesn't change and there is no bar appearing on the top right corner indicating the change in brightness. This laptop has two video cards: nVidia 540M and an integrated Intel HD Graphics 3000. If the nVidia card is disabled in BIOS the top right bar appears but the brightness still does not change.
