Common Sense Precautions
The most delicate part of your prized possession - the Liquid Crystal Display (LCD) screen on your laptop can easily get damaged. Proper care is necessary to ensure the laptop screen is scratch-free and not damaged. The laptop becomes practically useless if scratched, cracked, or damaged.
Words of wisdom: "It is imperative that you take care of your LCD screen as much as possible and prevent it from being scratched." 
Next are some preventive steps in how to protect a laptop screen from scratches:
- Keep all sorts of objects well away from the perimeters of your laptop to avoid them falling on the computer screen.
- Avoid continuous touching or rubbing the laptop screen with an object which may cause damage to the delicate LCD.
- Avoid using a sharp edged cleaning utensil to clean the screen; otherwise, it risks being scratched.
- Invest in a good carrying case for the laptop to prevent denting or bumping the LCD screen.
- To clean the screen, just use water mixed with vinegar and isopropyl alcohol on a soft cloth. Alternative, use cleaning wipes.
- Avoid wiping off dust or dirt with paper towels or rags to clean the screen as these may result in leaving smears or scratches.
- Use a screen protector or screen filter (which are explained in detail next).
