Kensington lock
Updated: 01/31/2019 by Computer Hope
Alternatively called a K lock or K slot, the Kensington lock is small hole found on almost every portable computer made after the year 2000. Depending on the model of laptop, the hole is located either on the back corner or on the side.
Laptops with a Kensington lock hole can secure their portable device with a Kensington lock. The lock is inserted through the hole, with a cable attached around a secure location (e.g., table leg), so no one can walk away with the laptop while you're away.
