This hotkey should incrementally increase the laptop display brightness. It is a combination of "Fn" + "up". On the keyboard itself there is the standard "arrow up" icon accompanied by an additional icon resembling a dial (or sun) with a smaller arrowhead pointing up positioned above the dial (or sun).
