Nabi tablets not holding a charge is a common issue. The problem may be caused by the power adapter, power port, or the battery itself. Follow this troubleshooting guide to determine what the specific problem is.
Your tablet must have either a faulty screen or display. If there is visible damage to the screen, this may cause the touchscreen to be unresponsive. If the screen is undamaged and clean, then the problem must be the display, in which case it needs to be replaced. Follow this troubleshooting guide to determine what the specific problem is.
The issue may be the adapter cable or the “nabi” port itself. First, try a different port. If none of the “nabi” ports will read your device, then your adapter is faulty. If only that one port fails to read the device, then it is faulty and may be fixed following this troubleshooting guide.
