Here are a few things to try if your device is not powering on.
1. Check to make sure your device is fully charged.
Devices need to charge with a Lingraphica charger for a minimum of 6 hours every day (or overnight) to achieve a full battery life. Additionally, we recommend you power down your device while it is charging. Lastly, make sure you are using the charger that was provided, per the image below.
2. Reboot with the power button.
Press and hold down the power button for an extended time of 30-40 seconds.
3. Reboot with both the lower volume and power buttons (TouchTalk and MiniTalk only).
Press and hold down the lower volume and power buttons at the same time for 30-40 seconds.
4. Check the charger port.
The charger should fit into the charging port snuggly. If it feels loose or needs to be held in place, it is likely that the port is damaged. In this instance, the device will need to be returned for repair.
