If your Dell Chromebook 3100 2-in-1 has lost its ability to hold a charge, you most likely have a dead battery, which requires replacement. A functional battery provides power to your Chromebook. Eventually, Chromebook batteries will rapidly drain after going through a repeated amount of charge cycles. If you notice that your charged battery is draining more quickly than usual, you should replace your battery.
