I installed a win 7 rc 64x on my HP 6735s and surprised when find brightness control did not work correctly. When i try move brightness slide bar in power plans or in win+x app it slide back to minimum right now. However, sometimes it changes to 70% and brightness change too, but only in this session - logoff, reboot or hibernate - and brightness again goes to minimum.
fn+f keys dont work at all, only in bios stage.
I tried all drivers i can find - ati whql for win7, ati beta, hp keys for vista 64 - its all dont work. What can i do else? HP engineers know about this problem? In ms forums only one solution - hp will release correct drivers before win 7 starts.

Just go to www.hp.com -> Support & Drivers -> Step1: Download drivers and software (and firmware) -> Step 2: 6735s (your laptop model), GO -> Select HP Compaq 6735s Notebook PC -> Microsoft Windows Vista Business (64-bit) -> HP Quick Launch Buttons.
In fact, it's the same version for all Vista Edition, just choose 32-bit or 64-bit.
