Xiaomi Mi Pad 4 Shutdown Unexpectedly

[Luiso]

I bought a Xioami Mi Pad 4, a couple months ago and everything was going well until this morning that I was using it and suddenly shutdown with no obvious reason, no pop up advice or message that telling me something was going wrong. I have enough charge on battery, it was at 85 %, so I dismiss a battery issue. Now is death completely, do not respond, I plugged again to check if something happen, but not luck.
Please if anyone has the same problem or know how fix it, I will appreciate your support ..
