"Intermittent USB Power Port - Common Problem"に関する回答You can take apart the tablet and replace the charger port, it costs around 6 dollars, to buy a new port, you also need a soldering iron 15 watt, clean off old solder put new port solder in takes about 5 mins. To fix, 20 minutes to get it open and take old port out. I have been buying broken tablets fixing them and reselling. I am not a technician. I learn from YouTube. I am stay at home mom. I love electronics.
