Hoping to guard against such a scenario, some school systems are installing anti-theft protection software on their mobile computers.

One such solution, from Absolute Software, works like a Lojack system for a laptop. The tracking agent, called Computrace, silently calls into Absolute’s monitoring center each time a user logs onto the internet. If a Computrace-equipped laptop is reported lost or stolen, its location can be traced, and Absolute works with law-enforcement officials to recover the asset.

“Laptop theft is a fact of life,” said John Livingston, the company’s chief executive. “We really can’t get away from it. What we can do is help protect laptops from being stolen by using a product that can track notebooks with an embedded method and get them back if they’re lost or stolen.”
