T4500 CPU replacement or enhancement guide
Notebook CPUs cannot be replaced easily, except in rare situations. This is due to the fact that they are permanently attached to the motherboard, and swapping one requires purchasing a new board. If your laptop feels sluggish, overclocking it—raising its performance beyond its limits—might help temporarily. However, I believe it’s time to consider a replacement device or switch to a more efficient operating system like Linux.
Some T4500 units are often soldered, but G72 is a different story. You might be able to work with it, though there’s a chance it won’t boot due to compatibility issues. If you really want to try, you could go with T9900, 7250, or 7300—they all have the same TDP, so heat management should remain similar.
