I don’t have access to a computer with ALS chip, so I don’t have any experience with this. But check that your ALS chip is enabled, and Microsoft also states that Adaptive Brightness is not available in all Win7 editions (Have updated the article about these extra details).

I don’t have the enable/disable adaptive brightness option on mine either, yet it constantly changes my brightness and it’s driving me insane to the point that I want to snap my laptop in half. What can I do to fix it? I’ve tried changing just about any and all brightness options in about every combination I can think of.

Adaptive brightness can be stopped or set to manual by following these steps:

1) Windows+R
2) Type “services.msc” (without quotes)
3) Look for the service named Adaptive Brightness.
4) Double-click Adaptive Brightness to open its properties and turn off or set to manual.
5) ???
6) Profit

This service is convenient if your hardware has an ALS (ambient light sensor), otherwise it’s fairly useless.
