Battery Charging Problems
The device is not charging when it is plugged into the electrical outlet.
Faulty Battery Charger
The Hisense Sero 7 Pro charger comes with two parts; the USB adapter as well as the USB cable. First, try switching electrical outlets. The USB is most compatible when a 5v/2amp connected to the micro USB cable. Plug to outlet with nothing else being attached. If problems persist, try switching the USB adapter and/or cable. If the issue still exists, consider replacing the battery charger using steps given here: Replace Battery
Connect to Different Outlet
The electrical outlet in use may be the issue. Try changing to a different outlet.
Mini HDMI Input Issues
The HDMI cable is plugged into both the tablet and television, but no image or sound is detected.
Dust Inside Mini HDMI Input
One common problem with the HDMI connection would be excessive dust particles accumulated in the vents. To fix this, first unplug the HDMI cord from the tablet. Now, use a compressed air blower to blow air directly into the Mini HDMI port. Blow several times and connect HDMI cord back into the tablet. Test the connection once more and see if the problem is fixed.
Faulty Television HDMI Port
Another HDMI issue is a faulty television HDMI port. If there are multiple HDMI ports on the television, try plugging the HDMI cord to a different port. Once this is done, test the connection and see if the problem is fixed.
Wi-Fi Connection Difficulties
You are having trouble connecting to the Wi-Fi. After each step, try opening a web browser again to check for a successful connection.
Turn Wi-Fi On/Off
If your connection is not being detected, try to turn the Wi-Fi off and then on again on the Hisense Sero 7 Pro Tablet.
Consider restarting your device. This procedure usually fixes the issue of a bad Wi-Fi connection the majority of the time.
