Hello, I have Sony VIO laptop, model VGN-CS390c, it was stolen from my car a few days ago I can remember the last part of the serial number 7 digits but i dont have the first 8 digits of the serial, but i have the product ID number and the service tag number . Can I get the first part of the serial number? If yes can I use the serial number sfter that to trace the stolen Sony Laptop whenever its logged on to the internet by knowing the IP address and thus locating the region it is used in it ?
