Laptop and Electronics Theft

Never leave your laptop or expensive electronics out in the open if you are not present.
Use a laptop lock to secure your computer. Amazon sells a variety of cable locks.
Lock your doors and windows in your dorm or office even if you are only going to be gone a short while.
Consider engraving your birthday or personal serial number on your valuables so that you may identify them if they are stolen. Keep a list of the items and their serial numbers.
