I just got an iPad 5th generation and when I plug it into my MacBook Air 2015, it keeps disconnecting and reconnecting continuously. I plug it back into the power brick it works fine. I plug in my iPhone into my MacBook Air and it doesn't have this problem. I tried using brand new Apple lightning cables and still same problem. I plugged into MacBook air and did a hard reset by holding home and power and it started up with "not charging". Any suggestions?

What is your exact model of iPad 5th gen? Could I assume you have an iPad Air? What is the software version and your iTunes version?

Have similar problem with iPad 5 (2017). When connected to my laptop always get the "not charging" message despite it being charged!

I've noticed this as well. I'm guessing the device is pulling too much current from USB and the port is not able to deal with it.

Trying using the left USB port. The right side USB port on many MacBooks is shared with the camera, Bluetooth, and other peripherals already drawing USB power.

Yeah, I think it's just insufficient USB power draw. I have the same issue with my iPP 12.9 on my iMac via a powered USB 3.0 hub. But the powered hub is a POS. If I plug directly into my iMac no problem. It's just the hub that isn't able to supply enough power to the iPad. No problem with my mini 4 or iPhone 7 with that hub just the power hungry iPP 12.7.

Without getting more information, try these:
1. Plug it directly on the USB port on the Mac
2. Try the other USB port
3. Plug it in with the Macbook Air plugged to AC

I took it into apple repair depot and they replaced the Logic Board, trackpad, and Power supply. I'm getting it back today. See if it fixed the problem.

Eagerly waiting. If it gets fixed for you then I'll take mine to the Apple store as well.

Got mine back and they replaced logic board due to symptom No Power/Light, Power Adapter OK and replaced Cable IPD due to symptom Cables-Defective. So far so good, problem went away.

I wandered here for the same issue, and this fixed my problem. Oddly it's never been a problem before updating to High Sierra and iOS 11.

2014 macbook pro + ipad air 2

Either that, or all this time I've had these devices I've always had my mouse & keyboard usb in the right side USB port. Which is entirely possible.

I believe this is the solution to your problem: https://discussions.apple.com/thread/5453216

I have two iPad 5s. A 32 and a 128 GB. Apart from a false reading (“not charging” when it actually is) every time I plug it into my laptop, never have I had this problem regardless of which USB port I use.
