"The CPU upgrade is a little bit tricky on the notebooks and in most cases not advisable and not possible.
After the CPU upgrade it could be possible that the cooling modules don’t run properly and the notebook will overheats.
Why? Well, the new and stronger CPU produce more warmness and the temp would goes up. The fan table stored in the BIOS will not match with the new CPU and the cooling fans would work not correctly.
Furthermore the CPU upgrade will cancel your warranty! This is very risky!!!
Anyway, it looks like you want definitely upgrade the CPU??
So I would check the chipset installed on your notebook.
Try to find out the details of the chipset and search on the Intel page for the compatible CPUs"

thinking about it, if it was over heating, you could get one of those cooling tray things. Also go to a local pc repair store, they usually (we always did) have a few spare cpu's from dead laptops that may be compatible.
