Goodday,

Ive just bought a laptop wich contains both the HD 3200 Series (wich does work properly).

But when i want to switch to the High End it stops working.

When i for instance use Ati Power Express and click on High End CPU the poppup comes saying switching to Power Save GPU Complete.

This is while i click on the High End.

When i check @ System Management > Device Options > ATi Mobility Radeon HD 4530 / 4570. When clicking properties it says this:

VGA_ATI(M92)_v8.652.1_Win7x86x64  < ACER DRIVERS

9-9_beta_win7_64_dd_CC < ATI Win7 64Bit Drivers

9-10_vista64_win7_64_dd_ccc_wdm_enu < ATI Win7 64Bit Drivers

When installed i get same errors, except for when using WDDM drivers, because then the device (4570) cant start anymore.

Plz help me i tryed googling it for a week but cant fix it.
