Answer to "Why does my tablet have no sound output?"Before checking anything further, ensure that the volume on the device is turned all the way up, or that the device is not muted. After assuring the sound settings are working properly, diagnose if the problem is a dead speaker. Try plugging in a pair of headphones or an external speaker in to the audio jack. If you are hearing sound from the connected device, the problem is definitely the speaker and you will need to get it fixed or replaced. For more assistance, check out the Troubleshooting Page.
Answer to "Why is my device not charging when I plug in the charger?"If the device does not appear to be charging, the two likely sources are either the charger itself, or the battery. When you plug the charger in to the device, an indicator light should turn on showing that the device is being charged. If this light does not turn on, you should check the charger in another device to see if the charger is working. If the charger is in fact working, the problem is likely the battery. To further confirm, if you are able to hear the fan of the device spinning but the screen wont light up, the problem is the screen, if the device still seems dead, I would replace the battery.
