QRD SPARK N5 Q Button / HOME Key Not Working Troubleshooting Guide

The center Q button on the QRD SPARK N5 functions as the controller's HOME key. It is used to power on the controller, enter pairing or reconnection status, and perform certain system functions depending on the platform.

If the Q button does not respond, cannot connect to a console, or does not wake the system, the issue may be related to battery level, firmware status, pairing procedure, USB connection, or platform compatibility limitations.

Common Causes

Q button behavior can be affected by:

Low battery or deep battery discharge
Controller sleep or power state
Incorrect pairing procedure
Loose or charge-only USB-C cable
Old Bluetooth pairing records
Controller firmware version
Interrupted or incomplete firmware update
QRD BlackPill converter limitations on PS5

Issue 1: Q Button Does Not Turn On the Controller

If pressing the Q button does not power on the QRD SPARK N5, the battery may be fully drained.

Recommended Steps

Connect the controller to a stable 5V/1A USB power source, PC USB port, or PS4 USB port.
Charge the controller for at least 2 hours.
Avoid incompatible fast-charging adapters during normal charging.
After about 1 hour of charging, press and hold the Q button for at least 5 seconds.
If there is still no response, try another USB-C cable and power source.
If needed, perform a factory reset.

Issue 2: Q Button Works, But the Controller Cannot Connect

If the Q button activates the controller but the controller cannot connect to the console, the issue is usually related to pairing status, USB connection, or old Bluetooth records.

Recommended Steps

Reconnect the USB-C cable and make sure it is firmly inserted.
Use a reliable USB data and charging cable.
Power off the controller.
Press and hold the Q button for approximately 3 seconds to reconnect.
For Bluetooth pairing, remove old QRD SPARK N5 pairing records from the console or device.
Pair the controller again using the correct procedure for your platform.

For PS5 use, QRD SPARK N5 requires the QRD BlackPill PS5 Wireless Converter. Follow the official setup tutorial👉 How to Use QRD BlackPill PS5 Wireless Converter on PS5

Issue 3: Q Button Does Not Wake the PS5 Console

When QRD SPARK N5 is used with the QRD BlackPill PS5 Wireless Converter, the Q button cannot turn on or wake the PS5 console.

This is a converter-use limitation, not a Q button hardware defect.

Issue 4: Q Button Malfunctions After Firmware Update

If the Q button stopped working after a firmware update, the update may have been interrupted or completed incorrectly.

Recommended Steps

Download the QRD SPARK N5 firmware tool from the official firmware page.
Use a Windows PC and a reliable USB cable.
Follow the firmware instructions carefully.
Do not disconnect the USB cable or close the firmware program during the update.
After flashing, restart the controller and test the Q button again.

Firmware reference👉 QRD SPARK N5 Firmware Version V3.1.06 Release

Use firmware V3.1.06 or newer if available.

Factory Reset Procedure

If the Q button still behaves abnormally, reset the controller:

Power off the controller.
Locate the small RESET pinhole on the back of the controller near the left rear button area.
Use a SIM ejector pin or straightened paperclip.
Press and hold the RESET button for approximately 5 seconds while the controller is powered off.
Release the RESET button.
Press the Q button to restart the controller.

A factory reset clears temporary settings and may require the controller to be paired again.
