Notebook Medion Akoya can't turn outta nowhere - what is it?

Hi, in advance I'm not from the noodle soup therefore buzzing so I ask that no solutions are presented as "recharge battery…"

Basic information:
Last time, the Lappy was used yesterday before going to sleep and the power supply took place continuously. (assume that he turned off after 3 hours because of my attitude.)

Now, however, he can't turn on when pressing the power button.IT Species why this could be.

If it turns off badly then holding the power button for 10 seconds can help. Then try again.
