everything in laptops is soldered down
cant upgrade them unless it is a top tier model specifically made for such a thing
What he said ^
Sorry to say it but even if your laptop does have a traditional socketed cpu in stead of it being soldered directly to the board, you won't be able to replace it with an AMD chip. Intel HD graphics suggests the laptop doesn't have a discrete gpu, i.e. an iGPU on an Intel cpu.
The only real option you have for improving gaming performance is to get an external PCIe dock with a desktop gpu. But the price + the trouble of setting that up is completely impractical (for the most part). You're better off buying a gaming desktop.
