6970M ATI Laptop Backlight Dim

This is a copy from a post I made on AMD's support forums, which a total of 80 people have looked at in the last 13 days...so I thought I would try this here.

I recently updated my M17X-R3 6970m BIOS from stock to the newset version (off Dells website) A12. I was doing in this in hopes to finally update the ancient drivers for my 6970m GPU. (using the SG/PEG option).

Everything started smooth on the PEG, I was able to initially update to the 13.12 drivers and games just ran so much smoother! After a while of playing I noticed that there was a difference in the intensity from my main external monitor, to my laptop screen. This was never the case in the past, so I figured that I had to mess with some of the power settings, as it looked very similar to how it would look when I was unplugged and the screen would dim to around 60-40%. After hours of searching down this path I started to wonder if it was the drivers. So I did a clean uninstall, swept, and reinstalled clean. This is when I noticed something strange. After the clean install, the computer booted to my log in screen, I passcoded in, the screen was bright!! much excite...but then about 2 seconds after I logged in, the screen went to the "dim" look. So I restarted hoping that would fix it, and now it is just always dim. I am coming to you guys because I am out of options. I have tried (clean uninstalls, sweeps) 13.4, 13.12, 13.9...all the same.

 

Here is a similar issue on DELL communities, Mr. Fox made a lot of great suggestions to fix it. T ake a look!

 

Thank you for the reply. I will be able to look at this tonight, although I have been using DDU and uninstalling as he has described. One question, do you know the best place to find the "recommended Intel driver" for the igp? I would like to make sure I am using the proper drivers.

 

Well I was able to somewhat fix the problem, I now have a fully lit display and running the latest drivers. The main issue I am having now is that every time the computer starts up I get a white screen for about 2 seconds, then multicolored small vertical ribbons in the pixel columns on the right side of the screen, then it logs in like normal, no problems. I have no idea what that is all about...it does make me nervous though.

 

@ Isolace. Would it be possible to demonstrate what is the source of the problem (e.g. a registry key?) and what steps did you take in order to resolve the issue, or at least to get full brightness?
