Adding a physical lock and cable is a great way to help to prevent your laptop from being stolen. The lock you need for your laptop depends on if it has a security slot or not. If your laptop has a lock slot, it will work with many T-bolt configurations. If it doesn't have a lock slot then you'll need to get a lock that attaches to your laptop another way, such as with an adhesive. While no lock is perfect, these laptop locks will help deter potential thieves. Many thieves take things that are convenient and easy to grab. If you have a lock on your device, they're less able and likely to grab it and run.
