    HD 4000 doesn't wake up from energy saving (W7/64)




      Since a few days my HD 4000 (configured as third) doesn't wake up from energy saving anymore. After that it's also gone from Device Manager and Desktop Context Menu.Only a reboot will wake up the HD4000 again.


      Setup is: Win7/64, ASUS, P8Z77-V LX2, primary and secondary on Nvidia GTS450 (works perfectly) and third on HD4000. HD4000 driver is (that's latest).


      This setup worked fine for a long time but stopped working all of a sudden a few days ago. I can't say exactely when. I guess after one of the automatic updates. Highest ranking candidate is: NVIDIA Corporation - Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.2, Graphics Adapter WDDM1.3, Other hardware - NVIDIA High Definition Audio.


      But that's just a guess and unfortunately I can't check that because I cleared the system updates.
