Not sure about this. I am sometimes getting screen dimming and brightening when I minimise an application and the screen is only showing, it becomes brighter. Is this normal behaviour? I am running my laptop on battery power a lot of the time. I actually noticed this especially when I selected the waterfall landscape background in W7.
I have Intel HD Graphics 4600 and NVIDIA Geoforce 710M graphics drivers. My laptop is the Toshiba Satellite C50-A490. I had to install all the operating system and drivers myself as the laptop is sold with DOS only.
Is there any good free hardware test software that would tell me if I have a GPU, graphics card or other problem? I am certainly hoping and anticipating that this isn't a hardware problem but it would at least put my mind at rest.
Many thanks for any advice.
