There are a lot of people on forums that ask this question. In fact, I see a lot of people get refereed to my forum from a thread on another forum that has this topic and they are all in Pakistan and other non-US places. The laptop theft trade is big out there I guess.
I would be very leery about ripping off someone's laptop. Especially if they have LoJack for laptops installed. You can't get rid of it once installed and they WILL find you.
To answer the OP's question. Go to the manufacture of the computer!
