Hi friends I purchased Fujitsu amilo pi 1536 laptop a year ago. Since it is quite old so I was thinking to upgrade it. Well I donít have much idea about how to do it but should I upgrade it or change the entire CPU. Many of my friends told me to change the CPU. I am thus confused what to do since it is the matter of my laptop. Also can I change the CPU by myself or should I send it in to Fujitsu Siemens? Need suggestions.
