Why Is My Ipad Not Charging Even Though Its Plugged In. Press and quickly release the Volume Up button. A software crash is a pretty common problem that happens to a lot of Apple users.
You can troubleshoot the cable by connecting the iPad to your computer. If your iPad still doesnt turn on it may have a hardware failure. This can remove debris.
Because it appears to be doing so its almost certainly a software bug thats causing it to sporadically impact charging when its not supposed to.
Put the battery back in if you removed it. In such case the best way to get it fixed is to do something called a force restart also called the hard reset. Try blowing strongly air into your devices charging port. BTW coconut battery is usually correct apps on iPad usually get it wrong.
