can you post the exact Make & Model of your laptop or Serial Number?
Have you tried finding out if there are any BIOS updates to your laptop?
It is best to use your laptop manufacturer's AMD Graphics driver rather than AMD Generic driver since the Laptop driver is 100% compatible with your laptop.
Does you laptop have a discrete GPU card besides the Vega integrated Graphics?
I see that in device Manager it is show "Unknown Device" which could be your discrete GPU card not having any drivers.
All of the above can be answered when you post the exact Make & Model of your laptop or Serial Number.
