Cant really help anyone further than to give the advice to Update Bios (if old like F1/F2) then install ONLY the offered AMD Drivers + make sure the Engergy Settings are correct: in the Catalyst Controll Center AND in your windows engergy scheme.
It is very dissapointing to see that there still NO new AMD Video Driver offered from HP. (May 2012 Drivers are offered)
I tried installing NEW ones directly from AMD drivers-online > worked, BUT killed "Engergy-Saving-Mode" + "Hibernation" > caused a sys. crash without fail - couldnt do anything about it except installing the old AMD Drivers offerd by HP.
Just to repeat Shockwave/Blurey/myself.:
! Applications/Games will show the HD 4000 only, but will use the 7650M HD if it is set in Catalyst accordingly. (Higher FPS + better graphics will also prove that - trying a benchmark is also recomended)
