Interesting, I’ve never had a problem with my OT on its own, but the other day when I shared a power strip with a friend’s small Eurorack system that he uses for playing out (so really seriously, not big at all, maybe 7 monules) I had something similar happen - when he turned his on, all of my stuff (OT, Anushri, CZ101 and Tanzmaus - pretty minimal and nowhere turned off and vice versa. There was plenty of power available on the circuit (at most we were drawing around 300 watts between all of our equipment, a pair of monitors and the computer we record to) and we never did figure it out. Switching him to a different power strip on the same circuit solved it, so maybe we were just exceeding the limit of something in the powerstrip itself, although it didn’t trip the circuit breaker in it. Unplugging his Eurorack would make my stuff come back on. Weirder still, he has a slightly larger system in his home studio and we have plugged that in to the same shared power strip plenty of times with no issue.
This is the worst part.
Not sure, because he was playing Prodigy very loud, dancing and running everywhere naked.
OT’s problem is the worst for me, for sure.
I can’t rely on it. It seems between the socket and the barrel area. 
Your neighbor?
My 4.5 old crazy son. The neighbor is worse.
I had same issue with my second hand OT which I bought from Ebay. The socket was fine, no broken solder points. The fix is very easy, look at power socket on your OT. There is a pin inside, when you moving your OT or power cable it loosing connection with plug. Get a small screwdriver and bend this pin gently about 0.5mm. I have no problems at all since then.
Have to test it rigth now, that can be the answer, I read about it but didn’t try to bend it !
Yes, it seems that pin diameter is bit too small compared to the power adaptor plug. So fix is quick and easy, now I can move OT around when powered on, I can even rotate the whole plug in the socket. It never drop a power or reset it self now. Of course, for some people it still might be a loose power socket/broken solder points. But in my unit socket was stiff and with no bad solder points, also cable and power plug wasn’t damaged. So the inner pin was suspected and bingo!
Yes. Did it. Seems to work !
Too simple to be true !
Thanks a million, and viva Elektronauts ! 
(I’ll report if I have this issue again)
He’s back! 
I don’t feel like having brocken legs anymore…
Had this problem for ages both with MD and OT until today Ha best quick fix ever!
Always thought it was the psu …this def should be sticky in the service your device section if there is one
It didn’t last! I did it again 2 days ago, insisted a bit more to bend the metal part.
Repared.
I read it as broke a knife while eating Normandy 
I was trying to cut cheddar. 
Did you ever find a fix? Thanks.
What was your fix? Thanks
Bend it again. Or solder a different socket like an Elektronauts did. Can’t find.
Thanks! U mean bend the pin In the machine port itself?!
