CPU

CPUs are very simple to upgrade. A notebook CPU is pretty much same as the desktop ones. Mobile CPUs tend to clock a bit slower, consuming less energy and put generating less heat. The only thing to worry is to make sure it is supported by the chipset and the availability of the BIOS for it.

If the company sells the homogeneous model notebook with a higher CPU, most of the time works with issue. One to be highlighted while choosing CP is that Pentium 4 Mobile different from the Pentium Mobile so avoid trying it.

Looking for mobile processors can be tougher than finding the desktop CPUs. One can surf local computer shop, online retail shops or even eBay for that purpose. The best place to buy is eBay others might charge a little extra.
