#1 Check the Cable
#2 Check the Power Adaptor
Make sure the power adapter is original.
Check if the indicator on the power adaptor is on after connecting it to the power supply.
Check the output voltage of the power adaptor with a multimeter.
#3 Check for a Short Circuit
1. Turn M1 upside down, and use a Phillips screwdriver to remove the protective cover of the motherboard by referring to this video.
Note: Please refer to the video part at 02：57~03：30 to unplug the cable.
2. Unplug the right NO.1 power socket, and reboot the machine to see if M1 works properly.
If the issue persists, take a video of the working status of the motherboard indicator, and contact xTool tech support for further advice.
