Why Is My Ipad Not Charging When Plugged Into Computer. Connect it to at least one other computer to see if it charges from it or not. Your iPad is receiving enough power from the charger to operate but its not enough to charge the battery.
Among other things your iPads display may become black and charging can slow or stop completely. In rarer cases some users report needing to wake a device remove the Lightning cable and reconnect it. If it still doesnt charge try changing cables.
So it was still draining the battery only more slowly.
Most USB hubs also dont have sufficient power. Use a different power adapter or a different charging cable. Actually the difficulty isnt with the iPad but with the USB port. If you left your iPad on and it said not charging then it was actually not charging.
