Hello Kimo-Pryvt,
Through your words, I understand that you want to replace the core i5 processor in your laptop with that core i7 processor found on a damaged laptop. This purpose is nice and charming, but I do not recommend you to do that! Because there are lot of things you need to consider, and too many problems you would face with than what you have expected! Laptop computer, in my opinion, is an all-in-one product, it is a one, but not many ones used to comprise a system. So I do not suggest you to replace any component of your laptop unless something is wrong.
Best Regards,
Aaron Janagewen
