I have AMD Radeon HD 6700M Series and after i updated to windows 8 i can't switch graphics card from (Power saving GPU Intel(R) HD Graphics Family) to (High preformence GPU  AMD Radeon HD 6700M Series ) Can ennyone help me? 
 

Go back to the operating system that was on the laptop.  Laptops are for the most part all proprietary so trying a new OS on one is not a good idea....You should only install a new OS on reference hardware...i.e. a computer that you build yourself.

Also, AMD does not support switchable graphics so if you wish to continue down this path you will have to work with HP.
