Cleaning Your Laptop
- Screen: Use a soft, lint-free cloth lightly dampened with water or a screen cleaner. Do not spray liquid directly onto the screen.
- Chassis and Keyboard: Use a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid harsh chemicals or abrasive materials.
Troubleshooting
Common Issues and Solutions
- Laptop does not power on: Ensure the AC adapter is securely connected to both the laptop and a working power outlet. Check if the power button is functioning correctly.
- No display or blank screen: Connect an external monitor to the HDMI port to check if the issue is with the laptop's display. Try restarting the laptop.
- Slow performance: Close unnecessary applications. Check for sufficient free storage space on the SSD. Ensure Windows is up to date.
- Wi-Fi or Bluetooth connectivity issues: Ensure Wi-Fi/Bluetooth is enabled in Windows settings. Restart your router/access point. Check for updated drivers.
- Pixel defects on screen: As noted in the specifications, LCD displays may have a small number of constantly lit or unlit pixels. This is a manufacturing characteristic and not typically considered a defect unless it exceeds specific criteria.
- External USB devices not recognized: Ensure the device is properly connected. Try a different USB port. Update USB drivers if necessary.
