See the guide here from AMD for configuring switchable graphics:

I've never understood why laptop makers would go to all the trouble of engineering and selling Switchable Graphics and then provide little or no instructions for how they work. Almost all of the owners I've encountered over the years who have these don't even know it! It's a huge marketing failure.
Keep me posted on your progress as I will be here to help until the case is resolved.
