Well, my limited knowledge of laptops suggests that upgrading them is very difficult.

Upgrading processors anytime is at least a little difficult as you have to know that your mobo has the right connection for your new processor.

If you have to get a new mobo and processor for your laptop, I'd reccomend just getting a new one. It's expensive to buy separate parts for laptops from what I've seen.

What is it they say about silence being golden?
