Hello. I can't adjust the brightness of my screen in Windows 10. I adjusted my screen brightness by holding the Fn key and pressing f5 or f6 to lower or raise it in Windows7. Now when I do that, nothing happens.
I went into the display settings and tried adjusting the brightness bar there, but when I adjust it, nothing happens. more details below.
