Troubleshooting Guide: Xiaomi Poco M3 Power Button Not Working

Check for Physical Damage

The first step in troubleshooting a non-functional power button is to visually inspect the button for any signs of physical damage or debris accumulation. Ensure that the button is not stuck or jammed due to dirt or moisture ingress. Use a clean, dry cloth to gently wipe the surface of the power button and the surrounding area to remove any dirt or debris.

Perform a Soft Reset

If the power button is unresponsive, you can try performing a soft reset to reboot the device. Press and hold the Volume Up button and the Power button simultaneously for about 10-15 seconds until the device vibrates and the Xiaomi logo appears on the screen. Release the buttons and allow the device to restart. This process can often resolve minor software glitches that may be causing the power button issue.

Enable "Double Tap to Wake"

Xiaomi Poco M3 offers a convenient feature called "Double Tap to Wake," which allows you to wake up the device by tapping twice on the screen. If the power button is not working, you can enable this feature as an alternative way to wake up the device. To enable "Double Tap to Wake":
  • Go to Settings > Display.
  • Scroll down and toggle on the "Double Tap to Wake" option.

Use the Fingerprint Scanner

If your Xiaomi Poco M3 is equipped with a fingerprint scanner, you can use it as an alternative method to wake up the device and unlock the screen. Simply place your registered fingerprint on the scanner to wake up the device and bypass the non-functional power button. To set up fingerprint authentication, go to Settings > Biometrics & security > Fingerprint.

Perform a Factory Reset

If the above steps fail to resolve the power button issue, you can perform a factory reset to reset the device to its original settings. Before proceeding, ensure that you backup any important data as a factory reset will erase all data on the device. To perform a factory reset:
  • Go to Settings > About phone > Backup & reset.
  • Select "Factory data reset" and follow the on-screen instructions to reset the device.

Contact Xiaomi Support

If none of the above solutions work and the power button continues to malfunction, it's recommended to contact Xiaomi customer support or visit a certified service center for further assistance. 

The issue may require professional diagnosis and repair, especially if it's related to a hardware malfunction.
