iPad dead after Apple-suggested "erase all settings and data"

What did I do wrong. I bought a new iPad Air 2 and backed up my previous iPad Air 2 to the iCloud. Then I followed the Apple-site direction on how to get the data from the backed-iup old iPad to the new one: Step 3:

Go to Settings > General > Reset, then tap “Erase all content and settings.”

Did that.

iPad is now dead. No lights, (no wake-up even it I slap it around a bit), no response to "on" button or plugging it in to the iMac mothership or a regular outlet.

The bugger question is probably "Why do thesis things just happen to me?" Some event in a prior life I suppose.

Suggestions?
