dell vostro brightness adjustment keys not working

Sep 6, 2010 9:55PM PDT

Hello everyone, as you can see i'm new to the site, and i was wondering if any of you could help me out with this problem that's driving me nuts...
i have a vostro 1000, originally it's OS was Vista, however i have recently upgraded it to windows 7, but now the hot keys/function keys of brightness adjustment are not working anymore, all the other function keys are working except just those two. i believe it must be a driver or controller of some sort that needs to be reinstalled or updated, but i can't figure out which one...

could any of you help me out with this? it's getting to a point where beeing in front of the laptop is hurting my eyes

thank you

Dell Vostro Lap top Brightness
Feb 15, 2011 12:44AM PST

I am having the exact same issue. Updated from Vista to Windows 7. Now the lap top display is not bright and Fn not working for brightness control. Also screen is not sharp. Dull. I put resolution to highest setting. Still nothing. Any suggestions?

Just a thought.

I wonder if the person who upgraded this for you installed the drivers from dell.com as well as the apps that enable the Fn keys (hint? Dell QuickSet.)
