The SmartChk tablet is stuck at an Ubuntu loading screen with 5 white dots under it

Your SmartChk tablet has a power button near the top on the right hand side. Hard reset the tablet by holding down this power button for 10 to 15 seconds.

After the tablet is powered off, ensure the power cable is connected properly on both ends as well as at the adapter joint.

Ensure no hardware keys (volume or power) are stuck before starting the tablet. Briefly press each key one by one to release any stuck keys.

Power ON the tablet by keeping the power button pressed until you feel the tablet beep/vibrate briefly. When you hear it beep/vibrate, it means the tablet is about to boot up. Release the power button and wait for the tablet to boot.

If the problem persists, it could be a hardware issue and may require further remote troubleshooting. Route the ticket to SmartChk support at this point.
