Quote: "Short answer: Write it off. Sorry but there is little chance of finding that laptop again unless the person who stole it hands it to the police!. I know that is not what you want to hear but it is what it is.
The IP address would do you no good as it chances with every connection to the net. The serial number would do you no good unless the police was looking at the laptop in person. And as far as the MAC address it is really hard to track any thing by just the MAC address" - bryonhowley
I'm sorry, but I'm afraid you're going to have to let it go.
