Acer Iconia Tab 8 A1-840 Troubleshooting

The charging port is the small micro USB port where the charger plugs into the tablet. This may be broken, causing the device not to charge. If the port is visibly loose, then this is likely causing the charging problems. Try wiggling the USB cord to see if it will charge. If this does not work, then you will likely need to replace the micro USB port.
