HP switchable drivers have been modified by HP to work on your model laptop. If you read the sticky at the top of the forum, you will see that you must use drivers furnished by the manufacturer, the generic drivers from AMD will not work. So either go to HP support and get the latest drivers, or use Leshcat modded drivers...a link to which is posted in this forum.
