Actually that is possible. Some laptops have "switchable" graphics where it uses the low-power integrated gpu for non-gaming tasks, and then switches to a discrete gpu card when a 3d task is detected like a game.
If games only wont run, but other stuff is running, you need to find out if it has a amd or nvidia gpu and a onboard or onchip gpu for 2d tasks.
You might be able to disable the add on gpu so the laptop runs only on the integrated one. Of course most games wont run good on a intel gpu or chipset gpu.
