I have a hp dv7-4248ca laptop that I have upgraded to windows 10. Switchable graphics does not work and the system seems to boot up using the onboard gpu (ati mobility 4200). The device manager shows 2 graphic adapters:
amd radeon hd 6300m
ati mobility 4200
The hd 6300m is shown as "not working" but when I disable it and then enable it again the screen blanks and then comes back again like the system was switching gpus. The hd 6300 is shown as "working properly". How can I tell which adapter is actually being used?
