On the subject of laptop theft, password protect your BIOS and any boot device if your laptop has this feature. This won't prevent you from losing your laptop but it will render it useless to anyone who takes it. Don't use easy passwords either. When I get laptops like this the first things I try are password and 123456. Its not my job to question where these come from but I make very little to no effort if I believe they are stolen and the owner had no clue about any password protection. I really personally do not know how to break these passwords. The bios can usually be reset but most laptops store any security features on a seperate chip that as far as I know cannot be reset.
