My laptop is an older model where it has interchangable parts like RAM and CMOS.. Now I cant send it to the official Sony representatives, Actually it is a small issue and the guys down the street can do it.. I know Ill have to remove the battery before giving it to them, but I think they can easily replace other parts with lower grade ones.. I know there has to be a way to know if anything has been tampered with, Like a Checksum for hardware or something (Googling it didnt provide good results).
