Here's why the ipad won't charge:
(1) The charger has been damaged, or the iPad charging interface has been damaged, will lead to failure to charge, it is recommended to replace the charger test to determine the problem.
(2) If the iPad is connected to a computer that is turned off, asleep, or in standby mode and connected to a USB port on the keyboard, it may drain the iPad battery and make it impossible to charge it.
(3) If the current Mac or PC does not provide enough power to charge the iPad, the status bar will display the \"not charging\" message.
(4) If it is connected to a USB port on an older Mac, or connected to a USB port on a PC, keyboard, or USB hub, the iPad may not be able to charge.
