Laptop locks work a lot like a bicycle lock, keeping your laptop safe from thieves. Installing a laptop lock is a smart idea when you’re using the laptop at a coffee house, securing it to the table. Or, if your laptop has sensitive data on it, you may want to use a laptop lock at the office too. Always attach the far end of the laptop lock to a secure point that a thief can’t lift or move. The other end of the laptop lock will fit into a security hole on the laptop. Most models of laptops contain security holes specifically to fit locks. As you’re shopping for laptop locks, be sure the model you select will fit your laptop. Some laptop locks will open with a mini key, while others have combination dials.
