That Is A Mobile Processor! The i3-2310M!
So The Upgradability Depends On Wether Your Manufacturer Asus Does It!
Otherwise Upgrading Laptop Processors Are Impossible!
This is very, very, very wrong.
Manufacturer's rarely upgrade customer laptops after the fact.
Upgrading a laptop processor is not "impossible." by any means. If it is BGA "socket", then it would be impossible, however, the 2310M is not a BGA socket, it is a PGA socket CPU. It is socket G2 to be specfic. Here is a page about it: http://www.cpu-world.com/Sockets/Socket%20G2%20(rPGA988B).html
