If you frequent coffee shops with your laptop, it’s a good idea to invest in some security. The last thing you want is to be without your computer. Adding a physical lock and cable is a great way to prevent your laptop from being stolen. Finding a lock that is compatible with your laptop depends on the security slot. 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, and we've selected the best options.
