Tad bit of summary:
So I have had the "pleasure" of owning an HP laptop for a few years now. Since HP does not update their drivers for a long time I was stuck with AMD 8.3 drivers. I recently updated to 13.3 in a different way (as HP was not letting me update via AMD). Everything went fine, except the backlight to my display is very dim/not on at all, and the options in the control panel will not raise or lower my brightness.

Question:
Is there anyway I can manually with some other application/script control my backlight brightness other than going back to 8.3(which is not in the question seeing as though most modern apps crash your computer with 8.3)

Laptop Specs:
OS: Windows 7 Home Premium 64-bit
Graphics Driver: 13.200.0.0
Graphics Card: AMD Radeon HD 6400M Series
Laptop: HP Pavilion dv7 Notebook PC

I think the problem is unrelated and is actually the inverter. Back in college - my buddy and I fixed about 8 of these with the same symptoms. It's a cheap part and easy to fix (just take off the screen bezel with 4-6 screws and it's at the bottom) –  nerdwaller Aug 9 '13 at 15:20
    
@nerdwaller The thing is I updated the drivers about 1 hour ago, and it broke literally right as the new driver was installed, and it was working before hand. Thus it is a software problem. –  Noah Huppert Aug 9 '13 at 15:24
    
Heard that many times before... But to verify, then I would suggest rolling back (just to make sure that's for sure the issue) before chasing it. Just my opinion from seeing this exact situation before (usually on dv2k's) - and that being the issue (amazingly timed every time). –  nerdwaller Aug 9 '13 at 15:29
    
@nerdwaller I will load it back, it sounds like some sort of powersurge might happen when updating that brakes the inverter. –  Noah Huppert Aug 9 '13 at 15:30

@nerdwaller I just updated the driver for my graphics card via windows. That seamed to do the trick. –  Noah Huppert Aug 9 '13 at 15:54
