Great news!  It was a bad power cord.   I bought a more "robust" looking cord on Amazon and everything powered on with no issues.   This other power cord will be receiving a negative review in short order. 
I bought a 1 TB Sandisk SSD for my Inspiron 3650.    Upon power up (after connecting) the LED on the Dell flashes amber and no boot up.    Is this the sign of a bad power supply or something I'm doing wrong?    All I want is a secondary SSD with which to store music and videos.
