I'm unable to adjust brightness on my lenovo thinkpad x230. I can't see the option in the control panel and the hotkeys for brightness dosen't work either.
I've tried to install lots of dirrent intel video drivers and all the drivers I could find on Lenovos website. I've also tried to remove all drivers and carefully install them again one by one.
I'm using Windows 7.
Do anyone know what to do?
