Suddenly turned off - iPad Pro 12.9 M1

Good afternoon, yesterday I updated to iPad OS 16.1, I was looking forward to this update and it finally arrived, I updated from the iPad, everything was fine, I was discovering everything new and working like every day with the camera and photo gallery, Today morning during a brake that I had, I left the iPad as always with the lid closed and when I reopened it it no longer turned on, neither by touch, nor with the power button, nor trying to turn it on or trying to turn it off, it was totally dead , I got a big scare since I bought it in April of this 2022, I thought it was the battery but in the same way when connecting it it did not turn on, well I searched the internet and managed to restart it by pressing the volume and power buttons one after another and well turned on and all good.

My question is if I have to take it under warranty or wait for it to happen again, since I don't know why it happened, if the same thing happened to someone, please share your experience to be aware, I would greatly appreciate it, I already made an appointment at an Apple certified center.

Many thanks
