long story short. I'm trying to downgrade my friend's Sony Vaio VGN-C240E laptop from Vista to XP. Unfortunately I ran into one final snag and it's a big one.

I have no way of changing the screen brightness. I was wondering if anyone knows how to do something similar to what was done on this blog.

Scroll down to Brightness Control Fix. It's a custom coded thing which appears to edit the ASPI settings. I REALLY REALLY want to do this but don't know how.

The reason it doesn't work for this laptop is because it was coded for a GMA965 card and this laptop uses a GMA945. Does anyone here have the knowledge or patience to help?

Thanks,
Emmanuel
