This action may direct pressure to the LCD and deform or crack the screen itself. Hold your laptop by the base: Lifting and holding the laptop by the display creates unneeded pressure on the hinges. Closing the lid using only one edge causes extra pressure on the hinges which over time will crack and break them. Close the lid properly: Close the lid gently and hold from the middle of the screen. Items like these can dent, scratch or even crack the screen. Prevent damage to the monitor: Make sure there are no obstructions (paper clips, pens or pencils, cats, motorcycles, etc.) on your keyboard when you are shutting the lid. Use an old clean toothbrush to clean parts of your computer: Cleaning around the keys on the keyboard, exhaust fans and around the bezel of the screen will help promote airflow and reduce heat buildup inside the laptop.

Have clean hands: Dirt and oils from your fingers and wrists can eat away from the protective finish on the laptop, keyboard and track pad. Keep food away from your computer: Crumbs can damage the keys preventing them from depressing totally, invite small bugs, damage circuitry and make the laptop look dirty. Keep liquids away from your computer: Liquids can damage or short internal components, corrupt data and make keys stick or not function.
