Phone dead, won't turn on anymore

[Menhir65]

Phone dead, won't turn on anymore. It was charged, I had just used it, when I realized it had turned off and there was no way to restart it. I tried to keep it connected to the charger anyway and then tried to turn it on in every way without success. Has it happened to anyone? How did you solve it? Can it be the battery or how do I think the motherboard?
It is still under warranty but given the bad reputation of the assistance service I would be tempted to show it from another service center in my city.

He has been in assistance for a long time but I have not yet seen my phone, it will be for the summer holiday period.
I hope at least they are able to solve and that they send it back working so I sell it and goodbye Asus.
