6. Troubleshooting
6.1 Connectivity Issues
- Wired: Ensure the USB-C cable is securely connected to both the keyboard and the computer. Try a different USB port or cable.

- Bluetooth: Ensure the keyboard is in Bluetooth mode and discoverable. Remove the keyboard from your device's Bluetooth list and attempt to re-pair. Ensure your device's Bluetooth is enabled.
6.2 RGB Lighting Not Working
- Check if the lighting is turned off or set to minimum brightness. Use Fn key combinations to adjust.
- Ensure the keyboard battery has sufficient charge.
6.3 Keys Not Responding
- In wired mode, ensure the cable is connected. In wireless modes, check battery level and connectivity.
- If only specific keys are not responding, the switch might be faulty. Utilize the hot-swap feature to replace the switch.
- Ensure the keyboard is not in a locked mode (e.g., Windows key lock).
6.4 Battery Life Concerns
