Hi robotncc,
Something similar might have happened to me, but mine was X1.
I was listening and realize the battery was at 30%, so I shut it down and charged it. It showed the charging indicator on screen so i left it. When I tried to turn it on again, I faces similar case with you. I already tried charging with several charger but nothing worked. Luckily the warranty was still active, so I sent mine to Japan for repair.
I hope yours will be back to work again.
thank you so much for your sharing! I contacted with amz dealer that I bought and I'm going to send to Japan for warranty
