K Slot
The interchangeable lock heads are compatible with three different laptop lock slots: Kensington K-Slot, Kensington Nano, and Noble Wedgelock. It's an ideal way to secure your laptop, such as HP Notebook PC or Dell XPS, or other devices such as monitors, docking stations, projectors, and drive enclosures. A Kensington Security Slot (also called a K-Slot or Kensington lock) is part of an anti-theft system designed in the early 1990s and patented by Kryptonite in 1999–2000, assigned to Schlage in 2002, and since 2005 owned and marketed by Kensington Computer Products Group, a division of ACCO Brands.
A Kensington Security Slot (or Kensington Slot, Kensington Lock or simply K-Slot) is a common device with which a laptop, notebook, monitor, or other movable piece of equipment can be securely attached to something less mobile. Kensington slots, conceived by their namesake Kensington Technology Group, have become the international standard for notebook security, and are almost universally approved by laptop manufacturers. This worldwide adoption has led to the name Universal Security Lock being applied, and laptop manufacturers ensure the compatibility of their devices with the lock. Computer equipment left in public areas are often secured using a Kensington lock with universities, colleges, libraries, internet cafés and large office buildings all making extensive use.

A laptop’s Kensington slot will take the form of a small, slightly elongated slot to the side or rear of the casing, with some space behind the casing to either side of the slot. A sturdy cable is anchored in this slot at one end using locking device. To the other end of the cable should be attached a heavier object such as a table or wall, for example. The locking mechanism inside the Kensington slot is secured and detached using a key- or pin-activated lock. It is important for manufacturers to ensure that the slot and lock combination does not block any ports or vents on the secured equipment.
A Kensington slot’s sturdy cable attached to an immovable object makes for a formidable opponent to the would-be thief. The weak point of the attachment is in the anchoring of the cable with the equipment itself, often to a thin plastic covering, and removal of the lock is a trivial matter of brute force. Substantial damage is likely to be caused by the removal in such a way, though, and a Kensington lock’s strength is in the deterring to opportunistic theft rather than in preventing it.
Variations on the standard cable theme are available, with extra-thin, portable and motion-sensing locks and cables all on the market. Adapters are available that enable equipment that does not have a built-in Kensington slot to be secured.
A Kensington Security Slot (also called a K-Slot or Kensington lock) is part of an anti-theft system designed in the early 1990s[1] and patented by Kryptonite in 1999–2000,[2] assigned to Schlage in 2002, and since 2005 owned and marketed by Kensington Computer Products Group, a division of ACCO Brands.[3]
Description[edit]
The system consists of a small, metal-reinforced hole found commonly on small or portable computers and electronics equipment such as laptops, computer monitors, desktop computers, gaming consoles, and video projectors, combined with a metal anchor attached to a rubberized metal cable secured with a key or combination lock. The end of the cable has a small loop that allows the cable to be looped around a permanent object, such as a heavy table or other similar equipment.[2]
The hole is found in most laptops, although a lock for it is typically not included. Occasionally, the slot is located so that installing a lock will also prevent the removal of a valuable subcomponent, such as a rechargeable battery or a memory module. The Kensington slot may be marked with a small icon that looks like a padlock with a capital 'K', or the slot may be unlabelled.

Security[edit]
Kensington locks are not designed to be an impervious protection measure.[3] Because most computer equipment cases are generally made of plastic or thin metal, the lock can be torn out, though not without doing significant visible damage to the case. The cable itself can be cut if an individual has a wire cutter or bolt cutter sufficiently strong to cut through the cable material, which will vary between different brands of cable. The Kensington type locks are useful to discourage quick grab-and-run thefts of equipment from casually supervised locations such as coffee shops, but cannot prevent the removal of equipment secured in an unattended location.
The key is often a cylindrical type, but there are versions which use a traditional flat key. There are also versions of the lock that use a numeric combination instead of a key.[3]
Alternatives[edit]
Several manufacturers offer similar locking mechanisms that do not require a special lock hole.[4] They attach to a popular port, such as the VGA or printer port, and have special screws to secure locks in place.
