Any suggestions on how to get it back on?
To eliminate the possibility of bad contact, you could connect it “directly” if you are handy with wires.
Below picture was posted as a joke in another thread, but in this case it would ensure connectivity. You could also monitor power consumption with USB power meter, if you have one, to see what’s going on, if anything.

In any case, if the battery fails to accept charging current, the cell voltage might be below threshold level and only service center could reset it. Battery replacement might be the last resort option, if all else fails.
