4. Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your laptop.
4.1 Cleaning
- Screen: Use a soft, lint-free cloth slightly dampened with water or a screen cleaner. Avoid harsh chemicals.
- Keyboard and Chassis: Use a soft brush or compressed air to remove dust and debris. Wipe surfaces with a slightly damp cloth.

- Display Issues: If the screen is blank, try connecting an external monitor to check if the issue is with the laptop's display. Ensure graphics drivers are up to date.
- Performance Slowdown: Close unnecessary applications, check for background processes, and ensure the cooling vents are clear. Update drivers and scan for malware.
