Explains how to restart Echo Dot. Restarting, otherwise known as rebooting, often corrects unusual symptoms that these devices may have.
How to Restart Echo Dot: No Power Button
Now none of the Echo Dot speakers that have come out so far have a power on / off button. So you restart these units by unplugging them for a brief time. That is, disconnect them from AC power for roughly fifteen seconds. Next, reconnect them to power again. Once the speaker finishes booting, and the light ring darkens, then successful restart is complete.
How to Restart Echo Dot: No Restart or Reboot Buttons
Note that Echo Dot speakers, have no physical reboot / restart button. Nor can you remotely restart it via the Alexa app.
So currently, the only way how to do this is power cycle the speaker, as described earlier. That is, power it down for fifteen seconds, then power it up again.
Restart Differs from Reset
Also note that RESTARTING an Echo Dot is not the same as RESETTING it. By restarting, we mean simply rebooting these speakers. But resetting does much more than this. Unlike a simple restart, resetting erases any stored settings and data in the speaker. So this involves more work afterwards to get the unit running once more. Thus, please do not conflate the two terms. This is especially true if you wish not to change the Amazon account or WiFi network information that the Echo Dot currently uses.
