The MF50 was disassembled to gain access to the PCB and battery. After disassembly, battery voltage was determined to be normal (7.32V), suggesting that the fault lies with the circuitry detecting the low power condition rather than the state of the battery itself. | The MF50 was disassembled to gain access to the PCB and battery.

The device was reassembled and left to rest for a few days. It was then plugged in again, and after an hour of charging it decided it would like to work again. I will update this page when this issue reoccurs, as it happened once before but resolved itself much quicker. | |||

DEVICE NOT CHARGING / LOW POWER INDICATION
After charging overnight, the device still showed a low power indication (three blinking lights) when attempting to turn it on. During charging, the area of the handle with the PCB felt warm to the touch, and the USB-C connector of cable used to charge it was unusually hot.
Step-by-Step Diagnosis
The MF50 was disassembled to gain access to the PCB and battery. After disassembly, battery voltage was determined to be normal (7.32V), suggesting that the fault lies with the circuitry detecting the low power condition rather than the state of the battery itself.
