I just setup w7 on my HP pavillion dv6i using vista 64-bit drivers downloaded from HP website. Everything is working properly except the screen brightness and volume Fn keys. These keys work during starting up and welcome screen but they could not be used after log in. I can only adjust the brightness and volume via windows mobile device center. That why I think that this windows' function is blocking or conflicts with Fn keys. Is there a way to disable this function or another way to get the Fn keys work? I would be greatly appreciate for your help. Thank you.
