Laptop CPU Upgrade?

[ShizZy]

Hey, my laptop has a Mobile AMD Sempron 2800+, 1.60 GHz, 256 KB. I'm not exactly sure of the socket, or where to find it, but I've heard that semprons use socket 754 (may only be some of them). Is it possible then for me to upgrade to something allong the lines of an Athlon Mobile 3200+ 64?

Edit: Model is a Compaq Presario M2200 Notebook.
