I recently bought a lenovo Laptop and was using it while charging and turned off what do I do?

I recently bought the lenovo ideapad 80TJ and was using it while charging. But then all of a sudden it turned off and won't turn back on. I have tried charging it, I've tried researching what happened to it but I can't find a reason why it turned off and won't turn back on.

New items have a warranty. Pursue that with Lenovo.
Used purchases probably don't, so see seller or a repair person.
That is all that can be suggested from your information.

If it's still under warranty exercise the warranty and send it back and get a new one
