I just got a new Vaio laptop. It is great.

However, the ambient light sensor dims the screen brightness and prevents me from changing it.

Is there a way to disable the ambient light sensor and go back to manual screen brightness?

Look under the Vaio Control Center » Display » Automatic Brightness Settings and uncheck the "Adjust brightness automatically" option.

If that doesn't work, go to the graphics properties control center: Right click on the Desktop home screen and select "Graphics Properties" > select the "Power" tab > select "On Battery" > and under "Display Power Saving Technology" click OFF

In case the solutions from the main answer are not available (formatting the drive and reinstallation of the system, etc.):

Run services.msc - and there is an option called "Adaptive brightness". You may want to disable that.
