I know this problem about old drivers for HP's laptops (with Intel HD Video and AMD Radeon HD hybrid graphics), I own Pavillion DV6 with i5/HD3000 and Radeon HD 6770m.
The only solution that I know it's the custom drivers from Leshcatlabs (google it, I don't know if it permissible to give a link here).
This custom pack contains both of Intel and AMD drivers (of course modern versions) and makes possible graphic's switching.
And yes, if you are interested you should read manual on their site.
