Need to look into how to keep
+3V3(STBY) suppliy alive long enough
after 19V DC or battery supply has been
switched off to perform controlled
shutdown.

to detect dc supply
Drain on battery due to detect ckt:
I = V/R = 16.8/67k = 250uA
Battery capacity = 2.3Ah
Time = 2.3/250u = 9200h = 383days
So, current draw by this bit is insignificant c.f. uC standby current
