Answer to: My tablet won't turn onYou may have no alternative but to perform a hard reset. Hold down the (Volume -) button, then hold down the power button. Release power button once Dell logo appears but continue to hold (Volume -) until menu appears. You can use the Volume + to navigate the menu, Volume - to engage. If it still does not turn on, reseat the battery before leaving the device overnight to charge and then try again. You can reseat the battery by carefully prying the case from the display (it is not screwed or glued down) with a small knife or screw driver. Pay special care around the buttons and USB/Memory ports. Carefully unplug the battery's ribbon cable and put it back. If this still doesn't work - your device is pooched!
