So I upgraded my old laptop from windows xp to windows 7. It was kind of buggy cause I needed to get some drivers again, like for the mouse, etc. But now the controls that allow me to dim and brighten the screen dont work. Normally I press Fn+F5/F6, but this no longer controls screen brightness. Am I missing a certain driver or something? I tried going to Sony’s website and downloading the drivers I thought would fix it, but either its not a driver problem or I installed the wrong ones. Could someone help me find the solution to this problem? (If it is a driver problem, a link to the driver would be greatly appreciated). nnMy laptop model is Vaio Vgn-Fe670GnThanks
