Question from abhishekvaid19967 : "Laptop show graphics card not connected"

My Laptop yesterday started using my processor graphics and not my amd graphics card for gaming. It had switchable graphics features. When I opened my device manager it didn't show my amd graphics card but showed Intel processor graphics. When opened Hidden items amd graphics card showed up then I clicked on it a window pop open describing it and showing status graphics card not connected. Now how in the world can a laptop inbuilt graphics card got unconnected. Please help. THANKS IN ADVANCE
