There's a button in the top left corner of my laptop that works as a method to switch between onboard graphics and the dedicated graphics card, but for the past month or two it hasn't been working. When I push it, nothing happens. I went to the Asus website and, as far as I know, installed pretty much everything there, but to no avail.
The FN key also doesn't work, except to turn off or adjust the backlight. But volume controls and everything else doesn't work.
