5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Keyboard not responding | Loose USB connection, incorrect port, driver issue. | Ensure USB cable is securely plugged in. Try a different USB port. Restart your computer. Reinstall keyboard drivers via Device Manager. |
| Backlighting not working or dim | Brightness setting too low, software conflict. | Increase brightness using Fn + F11. Check Razer Synapse settings for lighting effects. Ensure Synapse is updated. |
| Keys not registering or "wobbly" | Debris under keycap, keycap dislodged. | Use compressed air to clear debris. Gently press the keycap back into place if it feels loose. If a keycap is detached, carefully align and press it back onto the switch stem until it clicks. |
