Notebooks of all brands and in all price ranges have featured the small little rectangular hole on the case for years now that is specifically designed for Kensington locks. These locks use cables attached to the desk or another object that is hard or impossible for a thief to make off with. Kensington has unveiled the latest generation of notebook locks that still makes use of the port that is on notebooks today.
The new lock is called the ClickSafe and it has a separate portion that plugs into the port on a notebook whereas the older lock design had the portion that connects to the notebook built into the lock itself. Once the separate ClickSafe nub is placed into the notebooks Kensington port, the ClickSafe lock can simply be clicked onto the port for fast security when the user needs to walk away from their notebook.
There will be several version of the ClickSafe notebook lock offered. A keyed consumer version of the lock will sell for $49.99 and has the features you expect from a Kensington lock. The lock head is tamper proof and no key is needed to lock the notebook down unlike older versions of the lock. The steel cable is the strongest physical security on the market. A key is required to remove the lock from the computer.
