One last thing to try, can you remove the battery and plug in the USB to power it? Does it start without the battery installed?

Yes.

So that is a "yes, the calcualtor boots"?

If so, your battery is bad I think. Else you could also try getting the calculator all booted up, leaving it plugged in, and replace the battery while running. Leave it for a bit after that and see if it starts charging.
