Yes I faced your issue/s (some of which you may not have faced yet) and resolved them, you may have noticed that I also have an HP notebook with similar hardware to yours; I actually have a very long experience in IT.
Both Microsoft and its partners were/are aware of the outstanding issues for the various hardware and they are working to resolve them, but Microsoft needed to meet Windows 10 target release date. Hence, solutions will probably start showing as work arounds soon, due to public pressure and proper resolutions will probably start showing in the 4th quarter of 2015.
Simple.
