Laptops are so tuned to the final design that it's rare to see anyone change the CPU. What's in stores like Fry's are desktop CPUs so for others you get on the web. But you left out the make/model so I can't do more looking for you.
I've been thinking about upgrading my laptop's CPU, so I downloaded this "cpu-z", which shows me that the socket for CPU is "Socket 947 rPGA". The problem is I can't find such socket in any stores. Is it even possible for me to install a different CPU?
