VAIO Screen Constantly Dimming

I am running 64 bit Windows 8 on a VAIO touchscreen laptop. Yesterday, my screen started randomly dimming itself. When I went to change the brightness back up, as I held down the button it kept jumping back to a low brightness. When I tried setting my brightness in the power options, it would save to be bright for a little while, then after a time it would dim again. Upon checking the settings, it set it self to have near minimum brightness. No solution I have searched online has helped; my PC does not have adaptive brightness and my graphics drivers are up to date. Does anyone have any possible solutions?

This sounds like a light sensor... I know my old Vaio had one... You probably have to disable this in the Vaio settings.
