In order to upgrade the processor on this system, the entire mainboard must be changed along with the CPU. All of these processors are ball-grid designs - they're hard soldered to the mainboard and not removeable. The cost for the board+CPU will be 50% or more of the cost of the system initially - and you will lose your warranty in the process. In other words, forget it - if you need a faster system, sell the existing one and buy a new notebook.
