I have a Sony(Vaio) laptop that has windows vista home premium 64bit, the model is vgn-aw190c. I changed it to windows 7 ultimate 32bit. Now I have a problem with its function keys such az volume -/+ or brightness -/+,...; they do not work anymore!
I get some information about installing some software in order to fix it but I couldn't find all of them and I don't know if this way is correct or not, please some one help me about this matter.
