Dude, get a new one, therez no way u gonna get it back, tell it to cops, they will ask for service no. or serial no. and tell u that if they find it in pawn shop then they'll let u know, and u know that aint gonna happen. Unless you have lo-jack software installed, heard ,if some one  connects to internet, its gonna locate where ur comp. is other wise forget it.

Good luck.
