3. Maintenance
Proper maintenance ensures the longevity and optimal performance of your laptop.
3.1 Cleaning
- Screen: Use a soft, lint-free cloth lightly dampened with water or a screen cleaner. Avoid harsh chemicals.
- Keyboard and Chassis: Use a soft cloth. For dust in crevices, use compressed air. Avoid spraying liquids directly onto the laptop.
- Vents: Regularly check and clean the cooling vents to prevent dust buildup, which can impede airflow and cause overheating. Use compressed air to clear dust from the vents.
3.2 Battery Care
- Avoid fully discharging the battery frequently.
- If storing the laptop for an extended period, ensure the battery is charged to approximately 50-70%.
- Use only the original GIGABYTE power adapter provided with your laptop.
3.3 Software Updates

4. Troubleshooting
This section addresses common issues you might encounter with your GIGABYTE G5 MD-51US123SH laptop.
- Laptop does not power on:
Ensure the power adapter is securely connected to both the laptop and a working electrical outlet. Verify the power outlet is functional. If the battery is completely drained, allow it to charge for a few minutes before attempting to power on. - Display issues (no image, flickering):
Check if the laptop is powered on. Try adjusting the screen brightness using the function keys. If an external monitor is connected, try disconnecting it. If the issue persists, connect an external monitor to determine if the laptop's display or graphics card is at fault. - Overheating or loud fan noise:
Ensure that the cooling vents are not obstructed. Operating the laptop on soft surfaces (like a bed or lap) can block airflow. Consider using a laptop cooling pad. If fan noise is unusually loud or persistent without heavy load, ensure all system drivers are updated. Persistent issues may indicate a hardware problem requiring professional service. - Poor performance:
Check for background applications consuming excessive resources. Ensure your operating system and drivers are up to date. Run a virus scan. Consider increasing RAM or upgrading storage if performance issues are consistent across various tasks. - Keyboard or touchpad not responding:
Restart the laptop. Check for any physical obstructions. Ensure touchpad is not disabled via a function key (e.g., Fn + F10). Update relevant drivers from the GIGABYTE support website.
