At this point we appear to be headed into the realms of component failure. But if we’re lucky, the part that is misbehaving may be cheap to replace. Fingers crossed.
Set up the iPad, cable and plug as before – keep everything the same – but this time, plug into a different power outlet (or into a different USB port on your Mac). If it starts working, congratulations! Your power outlet (or USB port) is broken. Okay, that’s not ideal but at least you know.
If it still won’t charge, keep everything the same but this time use a spare charging cable or borrow one from a friend. A
new charging cable is relatively expensive at £19/$19 (for iPad Pro 2018 owners, the
USB-C version costs the same). There are alternatives, however: you can purchase a third-party
MFI certified cable from Amazon or read our roundup of the
Best Lightning cables.
Finally, do the same with the plug adapter on the end of the charging cable. A
new 12W USB power adapter is also £19/$19.
If your cable or power adapter is at fault, it’s possible you may be able to fix it, although in almost every case we would strongly advise paying for a new unit instead – the words “amateur repair” and “mains power” should never appear in the same sentence. But if you wish to consider all your options, have a look at our article
How to fix a broken iPhone or iPad charger.
If none of these substitutions work, it’s most likely your iPad that’s misbehaving. If that’s the case, we need to get help from the professionals.
