Sometimes iPad is not charging and you think that it is hardware problem or the connector issue but many a times it is the software issue. Here below find the best 5 ways to fix your iPad if you are not able to charge. If still the problem persists then you can contact Apple support for sure.
1. Try a force restart
One of the first and easiest things to try is a forced restart if your iPad is not charging. Press and hold down the Sleep/Wake button on your iPad. While continuing to hold the Sleep/Wake button, press and hold the Home button or the Volume Down button. Hold both buttons as the screen turns off, and keep holding them until the screen turns back on and displays the Apple logo.
2. Try changing switch outlets or ports
Sometimes outlets or USB ports just don’t work. That’s especially true if you’re plugging into a wall or computer you’ve never plugged into before. It can also happen if an electrical or other problem occurs in your regular outlet or port. So, make sure you try plugging into a different outlet or USB port and see if your iPad starts to charge.
3. Try switching cables
As said above that outlets can fail same thing is with the cables. Sometimes they get chewed up by the wear and tear of travel or even household life. Also especially for third party cables, defects catch up with them. If there’s no problem with iPad, and no problem with the power source, you need to check the cable in-between.
Better try a different cable. If you don’t have one handy, borrow one from a family member or your friend. Just get your hands on a cable or two other than your regular one and see if it works and charges your iPad
4. Restore your iPad in iTunes
Many a times restoring your iPad in iTunes also fixes this problem. iTunes is a safer bet than iCloud because it actually offloads, re-installs, and reloads your data rather than doing everything in-place and on your device. That can sometimes shake loose bad bits that even a forced restart or iCloud restore can’t. If you use an encrypted backup, it’ll even restore your passwords so you can get back up and running faster.
Connect your iPod touch, or iPad to iTunes on your Mac or Windows PC via Lightning or 30-pin Dock connector. Click on the Device tab at the top left then click on Backup. Wait for the backup to finish. Then click on Restore. Wait for the restore to finish. When you’re all done, try charging again.
5. If nothing works contact Apple
Finally if none of the above works and your iPad fails to charge then there could also be an issue with your battery. If you have Apple Care store nearby then run there to get it fixed. If you don’t, get an estimate and weigh the cost of repair against the cost of upgrading to a new device. If you don’t live close to an Apple Store, you can call their customer support in order to get it repaired.
