Lojack : Computer Hardware Buyers’ Glossary

LoJack is a service from Absolute.com that will help the police track down your stolen laptop. It does not require a GPS (Global Positioning System) unit in your laptop. If the thief reformats or replaces your hard drive, he will still get caught. It also lets you erase crucial files on a stolen computer remotely. It requires a compatible BIOS with Lojack hooks built in when it was manufactured. I believe it works by calling home to Absolute.com periodically and reporting its IP (Internet Protocol). It can further use WiFi (Wireless Fidelity) geolocation to home in on where the laptop is.
