Have you been able to confirm if there is actually a discrete video card in your system? I haven't been able to find anything to suggest it has - take-aparts show the 5560 having dedicated video on the mainboard. And specifications I've found say dedicated.
Is it possible you've taken your system's dedicated video to mean a discrete video card?
With a laptop, integrated generally means video incorporated into CPU or support chipset and sharing main memory, dedicated means a chip purely for the video having its own video RAM but normally mounted on the mainboard, and a replaceable card is discrete video.
