The 'Q' key on my Machenike K500-B61 keyboard isn't lighting up; what can I do?

If the 'Q' key on your Machenike K500-B61 keyboard isn't lighting up, here are some troubleshooting steps you can take based on the manual: Check general RGB lighting: First, ensure that the overall RGB lighting on your keyboard is working. You can try cycling through lighting modes by pressing Fn + \ |. Adjust brightness: The lighting for individual keys is part of the overall RGB system. Try increasing the RGB lighting brightness using Fn + ]. Disconnect and reconnect: Disconnect the keyboard from your computer and then reconnect it. This can sometimes resolve minor electrical glitches. Check keycap and switch seating: The manual suggests that if "Certain keys not working," you should "Check if the keycap is properly seated. Remove and re-attach if necessary." While this specifically addresses key functionality, a loose keycap or switch could potentially interfere with the LED contact. Re-insert or replace the switch: Since the K500-B61 features hot-swappable switches, if the issue persists, you can try removing and re-inserting the switch for the 'Q' key. Use the provided keycap puller to remove the keycap, then use the switch puller to carefully remove the switch. Align the pins of the switch and gently push it back into place until it clicks securely. If re-inserting doesn't work, consider replacing the switch entirely, as the LED is integrated into the switch itself. If none of these steps resolve the issue, it might indicate a faulty LED within the switch or a more significant hardware problem. In such cases, you should contact Machenike customer service for further technical support, as suggested in the manual.
