Can I upgrade my laptop processor?

you know i have seen it done to a desktop computer upgrading it to have more memory or you can add other features it didn't have before to make it better then it was and if you can do this with a desk top i bet you could do the same thing with a laptop i'm sure you can upgrade just about anything some computer places have the ability to do things for you or you can do it yourself i would ask questions to make sure your ideas are solid
