When "experimenting on my new machine I got hold of the wrong AMD chipset driver. This resulted in a few BSOD's before realizing the error, just unistalled this from Windows CP and Voila! (Use only manufacturer supplied drivers...)
Had a little difficulty getting the correct version of AMD Adrenaline software (also due to "user glitch:Me") Again, important to use WinUPD and/or Manufacturer drivers&software (but no trouble w/ nVidia's drivers, they work fine as this is the discrete GPU).
I recomend using the 'Terminate-icue'-software (on Github) for automatically disabling iCue-service start from boot saving battery + makes "Rainbow" colors on statup go away...
Also: Thanks to 'NikoB' for pointing out that color calibration is useful!
Battery is good for 4 h 33 m of watching Netflix (via wifi) on Low power mode w/ internal graphics ((Hybrid Mode) and max battery saving: 4h33m
Actually very pleased and happy w/machine!
