| neo1973 means GTA01, and don't have power from usb designed, so this

Thanks for the lesson Tony :-)  I saw it does have some charging
arrangement about USB power input, I just assumed it had the same plan
as GTA02.  But there is no VB_SYS.

Jay what I would do (but you have to factor in I do blow things up
sometimes) is remove the battery, cut up a USB cable, stick the A end in
my laptop and hold the black wire to 0V pin of battery connector, red
one to +ve pin of battery connector and see what happened when I powered
on.  pcf50633 is good for 6V abs max and USB is 5V.  If you think it is
dead already then this can only do nothing; make it deader; or send some
sign of life.
