My MX Ergo suddenly turned off and would not charge.

Hi! I was using my MX Ergo earlier and it was working perfectly fine and fully charged but suddenly it turned off. I tried charging it but after five seconds the blinking light did not blink anymore. Tried to unplug and replug and the same issue happens.

Product is still in warranty but the device was purchased in the US as a gift and I am currently in another country so self-repair might be the only option (no service repair centers in the country as well). Any tips on what to do?
