Dropped Xiaozhi 18650 won´t turn on again

Hello.

A friend dropped my Xiaozhi from ~1,50m and now I can not turn it on again. I don´t think it´s the switch because it doesn´t work without tailcap + wire, which was possible before, of course.
Before trying random stuff, I thought it might be a good idea to ask for advice on what I should do/test with it to make it work again.

Any tip welcome.

Thanks.

Check the wires to the led and driver probably one has unsoldered, check if the ring around the driver has good connection.
