Nintendo Sound Clock: Alarmo Has No Power

Nintendo Sound Clock: Alarmo

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

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

Before you start

You will need:

  • Your Nintendo Sound Clock: Alarmo
  • Supported power cable and AC Adapter
    • An AC adapter does not come with Alarmo and will need to be purchased separately.
  • Access to power outlet

What to do

  1. Check that the USB cable is securely plugged in to the USB connector on the bottom of Alarmo and the other end of the cable is securely an AC adapter plugged into an outlet that provides power.
  2. Confirm that you’re using a supported power cable and AC adapter that supplies 5V/1.5A/7.5W of power or higher.
  3. Check the cable and AC adapter for damage. Damage can include frayed or split cord, loose connectors, kinks, etc.
  4. Unplug the device from power.
  5. Wait 20 seconds then plug the device back in.
  6. Try a different AC adapter and cable. A Nintendo Switch AC adapter is compatible with Alarmo.

Situation not resolved

If Alarmo still won’t power on, your device will need to come in for service. For testing purposes, include the cable and AC adapter.
