Upgrading Laptop CPU

[Si_Hi]

I have a Toshiba Satellite C55T-A 5218. I had pulled apart the entire laptop and had cleaned it out after 4 Years. I realized after pulling the laptops heatsink the CPU had a little screw I could turn and unlock the cpu to take it off. After doing some research and looking for upgrades I want to know if anyone happens to know if I can swap out the Pentium inside it to an i7. It has a Pentium inside of it.(More details will be within the links.) I want to see if it swaps with any i7 that pulls 35 tdp. I will link any and all CPU's I'm looking at. I think I'm off to a great start with the research but I am leaving for 4 days and I hope Help is on the way.

Links:
Intel Pentium 2020M @2.4Ghz
Intel i7-3520M @2.9Ghz
Intel i7-3540M @3.0Ghz
Intel i7-3612QM @2.1Ghz
Intel i7-3632QM @2.2Ghz

It doesn't mention any other CPUs for it. There's a pretty good chance the bios won't support anything else.

The Pentium is actually 3rd gen, Intel just names Pentiums and Celerons differently.

The cooling solution in the laptop will probably handle the 2-core i7 without issue.

The 4-core QM chips have a 10W higher TDP and will often thermally throttle almost instantly when loaded on a cooling solution designed for 35W TDP CPUs.

Make sure that you have the latest BIOS, pick up one of the CPUs on EBay, and give it a go. Should be quite the boost.

I did a similar Pentium -> i7 QM upgrade with an Acer Aspire, which is one of my favorite computers I've owned (got it free, picked up the CPU + a different cooling pipe for one of these with discrete graphics from Ebay). Made a massive difference in speed. Both of the laptops I've changed CPUs in had no issue detecting higher-specced CPUs from the same generation (Nehalem and Sandy Bridge). If the CPU is supported by the chipset on Intel's site, you'll generally have no issue.
