Attach it to the carrying case and fill it out with your name. Make sure that no flap that covers your name. Attach something unique to the carrying case.

Your laptop will last much longer if it doesn't get damaged.  Don't attempt to twist the screen on its hinges, as this could crack the screen.

Purchase and use an appropriate laptop carry bag to buffer the laptop during transportation.  Correctly remove the wireless card (if applicable) before transporting. Always transport the laptop in a padded carry case, and avoid stacking items on the lid of the laptop. Clean the screen with a lint-free cloth. Avoid using window cleaner, such as Windex; the ammonia will dull the screen. Use a screen cleaner from a computer supply store. Think twice before adding stickers. Stickers leave a residue that can cause permanent damage or an unsightly mess.

Summary:
Know where your laptop is at all times. Treat the laptop with care. Protect the screen and body of your laptop. Transport with care. Keep the laptop clean.
