Thanks 🙂 . About the BIOS, yes You are right, I've founded it out. It is just a bit funny for me : There is an i7 4700HQ with own GPU which is disabled, They added a GTX770 which can not run on the battery, so it has to be underclocked. When it is undercocked it performes slower then the i7's GPU. Where is the logic here...? Atlest they could do the following : When on battery Enable the i7's 4600 GPU. Sad "all this horsepower, and no room to gallop" ...
