Upgrading CPU in Lenovo Thinkpad T410

[billfitch2you4me]

At the risk of over asking my question, I thought I should give a bit more info on my Thinkpad T410. I'm running Win 10 Pro with 8Gb of RAM. I'm very interested in upgrading my CPU to the best that my system will run. I have no problems at all with my machine, I just want to upgrade the speed of my CPU for better performance. If anyone can please help me in my desire for upgrading my CPU I will be greatly appreciative. I've tried to ask similar questions in different sections of the community, but if my questions (this is my 3rd) have ended up in the same place I apologize greatly. If anyone can help, I would be very appreciative!
Sincerely,
billftch2you4me Thank you!

I realize now that my previous query was too long winded. I recently acquired an Lenovo thinkpad T410, and my question is simply this: I have the 1st generation core i5-520M CPU rated at 2.44 GHz. I wish to upgrade the CPU to perhaps the Intel core i7-640M rated at 2.88 GHz which is touted as the best dual core processor of the Arrandale general for my Lenovo T410. My question is this to the forum-can I indeed upgrade to this better CPU? Any thoughts, insights, or feedback of any kind will be greatly appreciated! If the answer is no, will I be able to at least upgrade to the Intel core i7-620M 2.67 GHz?
Sincerely,

Does anyone happen to know what is the fastest CPU I can upgrade to? I have the Intel core i5-520 M 2.40 GHz, and want to upgrade to perhaps an Intel core i7-640 M 2.80 GHz or faster, but I don't know how high I can go? Any thoughts, suggestions, or feedback would be greatly appreciated!
