Hi, I bought this laptop about 2 weeks ago ( GL552VX). At first I could change the screen brightness from fn + f5 / f6 or from the manual menu.
But now I can not change the brightness of either the key or the menu. The fn keyboard works with the sound. Or with the command to light the keyboard. I installed another intel driver sent from someone from Asus and nothing. Has anyone met this problem? What can I do. 😞
