Thunderbolt display does not charge macbook pro

I found that the little wiggle room between the magsafe2 adapter and my MBP was the issue. If I position the connector in the upper right corner(up and towards you) of the port it will charge. Hopefully it works for some of you as well.

My problem is fixed by getting a new adaptor. I was skeptical at first, because the old adapter looks pretty clean. since i have a few of them stocked, i just opened a new one to try, and now it is charging. 🙂

After the same problem occurred after a few months with a replacement adapter, I realized after much thought is that I had been keeping my MBP retina elevated on a laptop stand next to the display, and that the cables from the display would pull ever so slightly downward on the connection to the MBP (the cable was routed behind the desk and back up to the display). I've removed the MBP from the stand and placed it directly below the display, and since then, it has only happened once that the charging light on the adapter connector didn't light immediately when the display was connected to the MBP.

FIXED: As others before, macbook + Cinema display = no green light, no charging.

SOLUTION: What worked for me was a Q-tip + rubbing alcohol and cleaned the bejeezus out of the Mag1 connector, the Mag adapter and the Mag2 receiver on my macbook. Works now!

I tried something that seems to work. I too have the adaptor. Multiple actually. What I did was remove the adaptor, plug that into The MacBook WITHOUT the power from the monitor in their. Then plug the monitor into the adapter while the adapter is plugged into the laptop.

Comes back to charging light everything on time now. Has anybody else tried this?

I've owned the Thunderbolt display about 5 years and use a MBP with it although most of the time it is connected to the i7 Mac Mini. As a general observation, one should be using the Display as a monitor only and connect your MBP or Mac Computer via the single lead that comes from your Thunderbolt display. The lead from the Display is a single thick cable 6mm in width terminating with a branch of two leads, one is a magnetic lead attaches itself with the MacBook Pro or in my case the MacMini which then plugs directly into the MacMini requiring no further leads. (This is a white plastic lead that plugs into my MacMini). I hope that you understand this procedure. It's a great monitor and works well with either the Mac Computers or the MacMini.

Clean the power port on the laptop and also remove the adapter and clean both connector surfaces and the power connector surface coming from the Thunderbolt Display. Once clean, the laptop will recognize the display and request charging, per normal use.

Hi I've got exactly yhe same problem with new macbook air

Hi I've tried another magsafe2 connector with no joy. Oddly if I connect an older Macair via the magsafe1 connector without the adaptor that charges !.

When I swap back - nothing !!

Hello

Hi I've got exactly yhe same problem with macbook pro retina 2013. I think this issue started since installed Mavericks =/

Any solution?

Hi, both my MacBook and Thunderbolt Display are less than six months old and used to charge perfectly. This problem for me only started with mavericks upgrade.

thanks, must be something to do with the connection.

regards

Mike

Thanks, I have some switch cleaner in the garage, just got to find it. I'll report back.

Well, Mike, from what you've said, it sounds to me like it is working. You could just remove the battery out of the MBP and just make sure the connections there are sound too. Good luck.
