Hi,
my Hi10X no longer turns on, when it is charging the led is green, when I press it turns red and then the led turns off. Even if I keep the power selected on nothing happens
Got the same problem. 
Once or twice logo chuwi showed up with “press and hold …” on the screen, or something similar, but i turn off to fast to read.
I just figured out, whats going on. Tablet is booting, but screen is down. If i touch it, it turning on for a moment.
I had a similar issue as I booted while hdmi was plugged in… after disconnecting the hdmi cable everything was normal again.
