Question:

“Could you provide expert advice on troubleshooting a Redragon Phantom Pro K629-CGO mechanical keyboard that has recently started experiencing connectivity issues? Despite having three connection modes—Bluetooth, 2.4G dongle, and USB-C cable—the keyboard now only maintains a stable connection via the 2.4G dongle. When connected via USB-C, it disconnects after a few minutes, and the Bluetooth mode fails to initiate pairing. I’ve attempted a manual reset, tested on different computers, checked power settings, and ensured no liquid damage to the PCB. What could be causing these problems, and how can they be resolved?”

Answer:

Connectivity issues with mechanical keyboards can be frustrating, especially when the device offers multiple connection modes. The Redragon Phantom Pro K629-CGO is no exception, and understanding the root cause of such problems is key to finding a solution.

The Bluetooth drivers might need updating or reinstallation.

–

Interference:

Other wireless devices can interfere with the Bluetooth signal.

–

Hardware Malfunction:

The keyboard’s Bluetooth module may be faulty.

Troubleshooting Steps:

1.

For USB-C Issues:

• Try a different USB-C cable to rule out cable damage.
• Check the power management settings for USB ports in the device manager and BIOS.
• Update the USB and chipset drivers from the motherboard manufacturer’s website.

2.

For Bluetooth Issues:

• Update or reinstall Bluetooth drivers.
• Remove other wireless devices to check for interference.
• Try pairing the keyboard with another Bluetooth-capable device to test the keyboard’s Bluetooth module.

Advanced Troubleshooting:

–

Manual Reset:

You’ve already tried the FN+ESC reset, but it’s worth repeating after other troubleshooting steps.

–

Firmware Update:

Check if there’s a firmware update available specifically for the K629-CGO model.

Professional Inspection:

If the issue persists, the keyboard may need to be inspected by a professional to check for internal damage, especially considering the previous liquid spill incident.
