I got an iPad that is not charging, connect the power cable does not show any indication of charging, and power keeps draining. Search around the web, it seems it is quite common.
I follow a few advises from the search:
- Use compressed air to clean the input socket.
- Force a restart.
- Switch outlets or ports.
- Switch cables.
- Restore in iTunes
None of it working. But, during test of stage 5, I actually got the iPad charged in recovery mode. And it only works in recovery mode when connecting to a computer, it won't work when charging from an power adapter.
That makes me thinking, why could it be charged under recovery mode but not normal operation? Hardware seems working, is it a software issue? But I have fully restored the iPad with no success. I search the web again, and found this one: Simple solution if your iPhone or iPad is not charging. It seems simple, and I took a toothpick and start picking the input socket, it does not have lots of lint coming out, just a little bit of dirt. And it works!
