    Nintendo Sound Clock: Alarmo Has No Power

    Steps for when Nintendo Sound Clock: Alarmo has a blank screen and won’t turn on or turns off when the alarm is sounding.

    Before you start:

    You will need:

    • Your Nintendo Sound Clock: Alarmo device.
    • A supported USB cable and AC adapter.
      • An AC adapter does not come with Alarmo and will need to be purchased separately.
    • Access to a socket.

    Note: Alarmo must always be plugged in to a power source to operate. The coin battery inside is intended to save settings in the event of a power outage but does not power the clock independently.

    What to do:

    1. Check that the USB cable is firmly plugged in to the USB connector on the bottom of the clock and that the other end of the cable is securely connected to an AC adapter plugged into a socket that provides power.

      • If any damage is found to the USB connector on the bottom of the clock, it will need to come in for service.

    2. Confirm that you’re using a supported USB cable and an AC adapter that supplies 5V/1.5A/7.5W of power or higher.

      • If the cable or AC adapter do not supply enough power to the clock, it may not power on or may shut off when the alarm sounds. Test the clock with a different cable.
    3. Check the cable and AC adapter for damage. Damage can include a frayed or split cord, loose connectors, etc.

      • If either is damaged, it will need to be replaced.
    4. Unplug the clock from the socket.
    5. Wait 20 seconds, then plug the clock back in.
    6. Try a different AC adapter and cable. A Nintendo Switch AC adapter is compatible with Alarmo.

      • Your clock will need to come in for service. For testing purposes, include the cable and AC adapter.
