I have purchased HP 15 AB108AX laptop recently for gaming but, while gaming, application is using integrated gpu instead of dedicated gpu..
i updated all the drivers also then it is not working..
If you go into the BIOS, there should be a section for Switchable Graphics Mode. Change that to Fixed, then see if the gpu is picked up properly by games.
I would also recommend contacting HP, as the system builder. We'll try our best to help you but the manufacturer will know more than us.
I would be careful with doing that, if the GPU is burned out or something then they wont be able to see the boot screen or any screen at all. I might be wrong.
