Obviously there is no doubt that the n150+ or any Samsung note/netbook have had problems with not being able to control their devices brightness on Windows 7. This is because any driver after the OEM driver would change a particular number in the registry(regedit)

There were two fixes to this problem in WIndows 7. The simple way was to install the original VGA driver. The other was to change a specific number to 84 in the registries.

I have tried both and still can't adjust brightness with the fn keys. I've installed Easy Display Manager which is the software required to use fn key functions. Sound works automatically with or without the software.

I'm wondering why I can't get this to work.

Anyone know how to fix this?

Just wanted to add that I have the same problem, also tried both fixes for Windows 7 and am running the Consumer Preview version of Windows 8.
