Lojack for computers - possible?

Having recently had my laptop stolen, I wonder why it isn’t possible to install something in a PC that will issue a cry for help under certain circumstances. Cell phones now routinely come with GPS software meaning that you could, I suppose, call up your provider and ask them where your cell phone is in the event it was stolen. This seems like a great idea for costly, easily stolen items like laptops.

Or how about an application that tells an ISP what phone number it’s dialing in from. That way I could report my stolen laptop to my ISP and they could set up a filter to look for the next time it came online.

These ideas seem to good for somebody not to have invented them already. Do such things exist?

Several products exist. This page explains several of them. It’s a great idea.

Been out for years.

Using Google searching under “stolen laptop alarm” I found …

A few months (maybe more than a year) ago was either stolen from the University of Texas and used elsewhere, or stolen from elsewhere and hooked up to a public Ethernet port at UT. In either case, the laptop immediately notified a system belonging to the proper owners of its IP address, it was quickly isolated, the goods recovered, and the suspects apprehended.

So, not only do they exist, they work, too.

Nice, I think I’ll look into that for my SOs laptop
