While experimenting with the Amazon Echo Show, I stumbled on the proper way to shut the device down. It doesn’t seem to be documented anywhere, so I figured I’d post it for those who need it. To shut down the Echo Show, simply hold down the mute button for about 3 seconds and then tap “OK” when the power off option appears. The mute button is the leftmost button on top of the Echo Show. To power the device back on, which essentially restarts it, just press and hold the mute button again while the device is off.
