Laptop screen brightness problem

Ughhh on 15/09/2014 - 13:57

Lately my HP laptops screen brightness has been going nuts. Changing from max bright, to dim, then max bright again every now and then without me touching/pressing any keys. Luckily this doesnt occur so frequent that it gives me a seizure, but enough to be very annoying (maybe every ~10mins). I noticed that doesnt happen when the charger is not plugged in.

Does anyone know a simple way to address this? Is this a primary symptom for something worse later on?

The warranty expired on 2014-04-20, but will this issue be covered by consumer guarantee?

Thanks

    It's a setting called Vari-Bright inside the AMD Vision control center. It auto adjust brightness using an ambient light sensor.

      Ive had a look in those settings, mine is the same screen, except it does not have the 'Enable Powerplay' and 'Enable Vari-Bright' checkboxes/option. Though it has the ability to select Max performance/powersaving ect in the drop down menu. This sudden change in brightness seems to only happen with the charger plugged in, nothing different when only running on battery. Ive re-installed the AMD Catalyst control centre from the original website, should be the latest compatible version. :(
