Check here for possible solution. > [@Chuwi Aerobook keeps switching off as if power button is stuck](https://forum.chuwi.com/t/chuwi-aerobook-keeps-switching-off-as-if-power-button-is-stuck/7230/17): > > Update to the solution of this problem: The keyboard/power socket has 28 pins. In normal operation, the power button shorts pins 27 and 28 to do a power-on action. Pin 27 should be at 2.0 V (or 3.1V if charger is plugged in) and pin 28 is at 0V (start counting the pins from the left, while looking into the socket from the ribbon side), when the keyboard ribbon is unplugged. On my Aerobook, pin 28 is somehow pulling down pin 27 to 0V if the ribbon is plugged in, even if I am not pressing down on… ---

Mine seems to be a similar issue. Will give this a shot.
