Reboot problem such as No command in Xperia Z5 Sony mobile.
Solution: The Sony battery is not removable. So, keep away until the battery power will getting low and it will become shutdown. Then recharge the battery and turn on.
It will work.
Hi @XperiaZ52,
I'm not quite sure I understand your question, but if you are asking for a way to power off your device when it's not responding you can do so in two ways.
Let me know if this helps or please elaborate further what you need assistance with.
I am not asking question but just giving help from my experience
I see, great to see that you sharing your experience with others, that is much appreciated! 
Hi,Emil
Sometimes it happens strange thing on my Z5, as normal working all right (navigating, Playstore, YouTube, whatever), suddenly stops responding the screen, a few seconds later, the screen turns black and turns on a red notification light, then boot the phone as if it was off. When it boot at all, the battery is 20% less than it was before. This happens not frequent but it bothers me. Actually it has android nougat .
I asked to support and she/he said that I need repair the device with XPERIA COMPANION, but seems it doesn't work....
Hi @JaviY,
I'm sorry to hear this. Is it that you can't do a software repair using Xperia Companion or that you are still experiencing the same behavior after you have completed one?
