Hey, 

I have a serious problem here, I can't control my Inspiron N5050 brightness.

here's the situation:

- the brightness bar is at the max.

- clicking on FN + F4 makes it go max - 1, and can't decrease any further. it's stuck between the max and the max-1.

- I went trying to use Dell Quickset to solve this but I've been suprised to find it not working.( clicking on the quickset.exe button nothing shows up)

I should probably mention that I formated my pc to windows 7 ( was on Ubuntu ), lost many drivers and downloaded them from dell website, did I forget something ? Have I made a mistake ? 

Please, help me as quick as possible, can't stand this light. goosh i'm going blind.
