The brightness slider (bottom right of my screen, on the task bar, near the date) has never worked. I can slide it up and down and nothing happens. It's been like this for about a year and I'm only just getting around to posting it here. It's of course not a massive issue, but it is annoying.
Can anyone suggest anything please? I saw another post that suggested a clean install, but if that's the only thing I can try, I will have to write it off as something just have to live with.
