*snif* Don't mess with a good thing *snif*

I knew I shouldn't have bothered changing drivers... I lost my brightness controls...

I have a HP dv9201ca with Nvidia 6150 and Vista. I'd been using the TweaksRus MobileForce X-treme G 101.70 M6 drivers for the longest time, they worked great. But so much had been released since then, I thought I'd give the 150 or 160's a try. What a mistake.

Firstly, even with modded INFs, Vista wouldn't recognize my card and they would not install. And the ones that did, I saw no difference. Now, I've gone back to the Xtreme G MobileForce Tweaksrus drivers, and I have lost my keyboard brightness controls. That is-- The Function key Fn+F7/F8 dimmer/brightness keys. And when I unplug my power cable, the screen does not automatically dim any more, despite the settings being set properly in the Power settings of Vista, i.e. reduce brightness by 25% when on battery.

What should I do? Am I f$^%? Is it time for a full re-install of Vista? What about HP's latest stock drivers from May? (I can picture everyone cringing at the notion)

What I don't understand, is how, by installing the 150s and 160s, deleting them, and going back to the TweaksRus ones, I lost the brightness control. I could understand the other drivers not support it, but since I've gone back to the TweaksRus 101.70s, I would think that the problem would be fixed.

Ideas? It's really important to me because I use the computer at night, and the screen is just too bright. I think I might be looking at... A FULL VISTA REINSTALL!!!!!!!!!! OH NO!!!!!!!!!

 

Probably it would work best to go back to the stock HP driver and then trying to upgrade from there to the original driver that worked for you and you should be fine.

 

I just installed the stock HP, and the brightness isn't working. You think I should now go back to the MobileForce TweaksRus driver, and you think it should re-enable it?

Edit: I just tried that suggestion too, installing the MobileForce drivers after the HP's, and the controls are not working. I am SO dreading a re-install on this, I have a feeling something so specific in the registry is changed, that I will not be able to fix it.

The unfortunate thing is, I think others have experienced this problem too, and some have fixed it... if I could only find out who, and how they did it...

 

Just figured it out. It wasn't the video driver at all. The monitor driver needed to be reinstalled on the laptop. The backlight and SmartDimmer work again.

Thanks!

 

glad you got it working.
