Some processors are actually built into the motherboard, and arent removable. I'm not sure if that is, but I would say that if you just want an upgrade, it wouldnt be worth the price or the trouble.
I never replaced a laptop CPU before, but I have taking apart laptops, and it's much more complicated then a desktop PC, especially when trying to put it back together
The 8200 is built in i serviced one before and it was a bad processer and it was built in and the dif. b/t the 850mhz to 1 ghz ant worth risking a laptop
