Power switch poblems

HI,

Every time I want to start the tablet, when I press the power button, nothing happens. I try a short hold and long hold but nothing. Then for some reason it does start, but quickly closes again.
Once It is open it is fine but how can I just click and have it start.

Thanks.

Please write to aftersale@chuwi.com.

Thank you. Will do now

What is the resolution for this? I have the same problem
