Answer to: No sound comes out of my headphones?Hi Donnelle, Please make sure that you hear a clicking sound when you plug in your earphones. If the problem still persists try resetting your tablet. I hope this helps.
Answer to: Why isn't my Dell Venue 8 7840 tablet charging?Hi Donnelle, Check if the charger port has any dirt accumulated inside of it because that can prevent it from charging properly. You should also see if the software is up to date because it is the software that decides if your tablet is going to charge. One other thing you can do is to check if the problem is with the charger itself. Use the charger with another device with the same port and see if it works. I hope this helps.
Answer to: My tablet won't connect to the internet?Hi Donnelle, This has happened to me before. Try closing all the apps, turning the wifi off in the settings and turning it back on again. If the problem persists check if your other devices are not having a similar issue because if they are then the problem is with the internet and not the tablet. Hope this helps.
