Hi All.New to the Forum..... Can anybody help me? I have a SONY VAIO FX604 laptop with a 1.1 Ghz Mobile Duron. I have heard rumors and read various articles suggesting that a CPU ugrade is possible as long as its power handling (25w) and FSB speed (200) requirements are kept. Has anyone done this? I've upgraded just about all I can on this machine apart from the CPU. I want to give it a shot....... Any help would be very welcome.
