i have just upgraded my HP dv3 laptop to windows 7. but instead of using win 7 home premium that HP sent along with their upgrade manager DVD, I used win 7 professional that i already had.
but before starting upgrade i used HP's upgrade manager to update BIOS, after that i installed win 7 pro and after the clean installation I again inserted HP's upgrade manager DVD as it said it had all the necessary drivers for my laptop. i have also downloaded all the drivers from HP site, and installed that were newer than the upgrade manager DVD.
everything has worked well so far, but im facing problem with changing screen brightness, it cannot be changed either by using HP's function keys (but functions keys work for everything else, like play, pause, stop, sleep) or via power options. even when i change the slider to change brightness it does nothing, brightness it stuck at 1 level. how can this issue be addressed? as at this brightness my battery drains too fast.
i have posted same topic on HO support forums, but still havent got any solution yet.
