my Asus N551JW's backlit keyboard only works on bootup, the function keys are all working the backlighting on the keyboard just wont work. any way to fix?
Have you tried pressing fn+F3 or F4? According to the user manual of the laptop fn+F4 brightens the keyboard back light and fn+F3 lowers the back light. If it will still not work, do install this hotkey software fix.
