The modern, ultrathin laptop is often equipped with a security port suitable for a standard lock head. However, the device is so thin that after the lock is installed, it may not be flat and stable since the lock is thicker than the laptop, causing uneven lifting of the device from one side. The slim coded lock is the strongest locking solution for ultrathin laptops and hybrid 2-in-1 devices equipped with standard security ports, allowing them to be flat and stable.
