M30U Won’t Turn On

Potential Causes

• Battery is too low.
• The device is still charging when you try to turn it on.
• The charging cable is not fully inserted.
• The cable, adapter, or USB-A port may not be working.
• The Power button was not pressed and held long enough.
• The Power button may be stuck due to dust or debris.

Troubleshooting Steps

1. Unplug the device before turning it on
   The M30U will not power on while it is charging. Please unplug the charging cable first.
2. Check the battery level
   When the device is powered off, short-press the Level button to check the battery.
   Each indicator bar represents about 20% battery.
   If only one bar is on or the indicator is flashing, please fully charge the device before use.
3. Check the charging connection
   Make sure the Type-C plug is fully inserted into the M30U device, and the other end is fully inserted into the USB-A adapter or power port.
4. Try another charging cable or adapter
   Use a 5V/2A Type-C charging cable and try a different USB-A adapter or USB-A port.
5. Press and hold the Power button
   Press and hold the Power button for about 1–2 seconds to turn on the device.
6. Check the Power button
   Make sure there is no dust, gel, or debris stuck around the Power button.
