The other day I stumbled across a nice Open source program that allows you to try and find your laptop if it is stolen. It can even use WIFI to try and get a location for you. The free version allows you to keep track of three devices, you can pay for premium if you need to. I installed it on my laptop and marked it as missing to see just how it works and it sounded an alarm and displayed a screen that said it was stolen. You can change the text displayed on the pop up screen from your control panel and customize what you want done in the event your computer is stolen or lost. It even has an option to snap a picture from your webcam if your laptop has one.
