 *Notice*: One issue commonly exists on M5Stick-C, which happens when the battery is at a low level. In this case, some of the devices will have problem powering on, this is probably caused by a chaos timing sequence of power-on of ESP32, some component is involved, such as AXP192, 552, ESP32.  There is one way to bring the device back to live: 
 - 1, Connect G0 to 3V3.        
 - 2. Plug in the USB cable. 
-- 3, The screen will light up and leave the USB to charge the device.
