I have a sony vaio laptop vgn-ax570g after installing vista home premium, the
fn hotkey does not work, so I can't adjust screen brightness. tried
installing sony updates, but whenever I try, the update states that it does
not recognize my model number, even though the updates are for my model
number. one update even said that the update I was trying to download was
for windows vista only, which is what I have, and it did not let me load it.
sony support sucks. any ideas??
