We know about most of the ports on our laptops as we frequently use them.While some ports like HDMI are rarely seen these days, modern ports like USB-C are now pretty commonly seen. But wait, did you ever happen to question why there is an oval shaped port on your laptop? Sometimes you can find a “lock symbol” next to it and other times you may not.
Today we will see what the oval hole is for.
Ans:- It is called a Kensington Lock, or Kensington Security Slot, and it provides an attachment point for a cable to prevent your monitor (or a laptop as seen in the picture below) from being moved or stolen.
— 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.
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.
