Are you using graphic drivers from HP or did you install drivers from AMD? HP drivers are what you need to use. You can download them at HP Laptop support/downloads. HP published a guide which is a good source of information on 'switchable' graphics regardless of which brand laptop you have.
Also, at the top of this forum is a sticky "Updating Mobility Drivers" which has more information.
