Q: Thunderbolt Display Power cuts off
Hello,
Hoping someone else can offer some insight to my issue. I have a 27" Thunderbolt display that I connect to a 15" Macbook Pro running 10.10.4. I have had the display for 2 years and it has been great until now. I use the magsafe to magsafe 2 adapter, and everything has worked just fine until the last 2 months.
Now, the whole display looses power randomly. It acts as though it has been completely unplugged. I can unplug the power cable and plug it back in, which sometimes works and sometimes does not. When that does finally work, the display works normally until it looses power again, seemingly at random times. It happens when I am working, and when I just plug the laptop in to charge. I have tried it plugged straight into the wall, thinking that it was the UPS, same issue. Sometimes it stays on for an hour, sometimes just a few minutes. Any ideas about what the problem could be? Is it toast?

Okay, I am marking this resolved for now. I took the display to the Apple store. The nice folks there kept it for two days and left it on. It never turned itself off there, and they could not recreate the situation. I brought it home today and it has been on since noon with no issues.
For anyone else with this or a similar issue, I suggest unplugging it, packing it up, driving 40 miles to the Apple store, and leaving it there where it will magically work just fine for two days and also when you bring it home. Alternatively, maybe just unplug it for an hour or so and then plug it back in...
