If your tablet can't turn on, please try to following methods:

If you press the power button, you can plug in the adapter charging for half an hour to 1 hour then trying to boot to see whether there is improvement;

2. Adapter or data line is bad
In other equipment (such as mobile phones, equivalent current and voltage plate) to test whether the normal charge, if not normal, please replace the adapter, charging line.

3. False crash status
Plug in the adapter to  charge the tablet , charging time is about 1 hour ,then long press the power button for 15 seconds to reset, after 5 to 10 seconds to restart the tablet.

An example of this thread being used for troubleshooting relevant issues: http://forum.chuwi.com/thread-3981-1-1.html

And one equally specific situation that doesn't seem to be covered by the content here of the OP thus far, so perhaps can lead to further expansion or refinement to include this situation: http://forum.chuwi.com/forum.php ... 5&fromuid=19651

Ribbon cable working (measured)
Battery at 8v = +- 90% full
No charger light, likely because battery is full
Tried the trick with power button long press
Tried with docked keyboard, but that doesn't help either
USB port is only powered for 15s after power button press (used a small usb led light)
No display nor backlight
No burnt components on motherboard and measured all R0 resistors. None bad.
Adapter does output correct voltage
No corrosion on the brand new USB-C port
5V rail available for 15s after power press
3.3V rail available for 15s after power press
CPU remains ice cold
No voltage on main bios eeprom (should get 1.8v) after power press
No voltage on main capacitor (330 µf / 16v) after power press
Unplugged/replugged battery... that's not it either...


I'm pretty sure it's a mainboard voltage regulator issue, but without schematics it's practically impossible to trace the problem.
So the list isn't very helpfull. It's a bit pity that the thing died after a couple of days without an obvious reason...
A part of the schematic would be helpfull (power conversion from battery to rails) and a bit of documentation on that KBC/EC controller ITE8987E would also be usefull.
Sending it back is no option, very expensive and little chance it will ever arrive.

I have This problem:

And my cable is broken(see picture).

I have the same problem. The flatcable makes a sharp bend and is pretty hard to remove from the connector. I wanted to look behind the motherboard to see if something was broken there, since the USB2 port is dead and had to disconnect the power/volume flatcable and it tore. My own fault. But still something that should be fixable. So I asked Chuwi support where I could buy one.

Chuwi support response:
HI
i am sorry , we don't have this , thank you

My Hi12 is worthless due to a $1 part.

If Chuwi is trying to become a serious player, they will have to seriously step up their after-sales and service. For instance keep some spare parts behind for breakage. Or give some to online stores to sell.
