Apple Thunderbolt Display randomly stopped charging any MacBooks...
recently, I put my MacBook Pro (2015) on my Thunderbolt Display to charge it up, as I always do. When I came back to it after a few hours, I noticed that it stopped charging, the laptop was around 60%. I tried re-connecting the MagSafe from the Thunderbolt Display and powered it off for a few minutes, but it didn't help - it seems that it won't charge any MacBooks anymore... The display functions normally otherwise, even though it makes a clicky noise when the brightness is at the maximum. It's very silent, but noticeable.
I did some research if this is a common problem, the only thing I found was that its sometimes the MagSafe converters that fail after some time. This is not the case for me, I connected an old MacBook (where the converter isn't needed to charge it) and got the same result - no charging.
The cable coming off the display is in pristine condition, no splits or fraying (yet), so replacing that probably won't solve my problem. The normal power adapter that came with my laptop still functions flawlessly.
My question would be if this happened to any of you as well and how could you fix this? Could this point to a defective logic board? Is it possible to have that repaired or should I get the whole board replaced?
Your help is very much appreciated!
UPDATE: See below what coconut battery indicates, in the bottom I specify the case.
