New information. With a fully charged battery, system will start. Updating repeatedly fails. Battery is draining to the tune of 15% in ten minutes or so when connected to a 2.1A wall charger. System will boot from sd card, system will not start with sd card w/ Jumpdrive -to fix the failed update issue. I would like to get the phone fully up to date to see if this is what is behind the battery drain issue, but this is looking to be moot. The usb/external power connection on the Pro seems a little finicky, something I've not seen before. I will leave the Pro connect to the wall charger for the day, anticipate it will fully drain the battery by my return. The four battery contact pins are not damaged, if that will help.
