I don't have much idea about this topic.
I have an old PC with a celeron processor and an old laptop with an i3 processor, could you theoretically replace the motherboards so that the PC has the better processor or is that not possible? Just around the pc)
It's not working. Laptops are completely different CPU sockets and the mainboards do not correspond to the PC standard format. If it is better, you can also operate the laptop stationary on the screen with a mouse and keyboard.
