Wrap one end of a laptop cable around a desk leg and pass it through the loop on the end to secure it. Laptop cables are approximately six feet long and are made with steel to prevent them from being cut. The locking mechanism on the other end of the cable plugs into a slot in the rear corner of the laptop that cannot be removed without the key. Some even have combination locks so you don't have to worry about misplacing the key. Kensington, Tryten and Computer Security Products offer a variety of cable locks that are compatible with most laptops. Chances are, any basic cable will fit. Still, check your laptop's documentation to be certain.
Install a desk mount cable anchor to reduce the chances of theft. It is used in conjunction with a cable to create a stable anchor point. Attach the mount to any part of the desk using the provided security screws or industrial-strength mounting tape. Instead of wrapping the cable around a desk leg, it goes through a loop on the anchor. The best use for an anchor mount is in cases where you cannot find a sturdy, immobile place to secure the laptop.
Secure a laptop locker to the surface of your desk. These lockers look like rectangular, metal lunchboxes that lie flat on one side. With security in mind, you cannot use the laptop while it is in the locker. Most are designed for an average-sized laptop, usually no more than 15 inches wide. Using security screws, mount the locker and place your laptop inside. No one can open the locker without the key, and the steel construction makes it nearly indestructible.
Invest in a portable laptop cart. Laptop carts or trolleys are similar to a small desk on wheels. Some can hold up to 60 laptops at one time, making them easier to transport. The carts are not only portable, but secure, with sliding guards to discourage prying. Most are used for storage and include features like temperature control, ventilation and power management for easy charging. Laptop carts include additional security methods like reinforced locks and alarms to discourage theft.
