My 30" ACD was replaced in 2012 by Apple. Then I didn't use it for two or three years. So it is still basically new. Like all sizes of ACD's it suffers from the "middle pin not working" in its power adapter, where you have to tape it off. I'm getting frustrated because the tape keeps wearing out due to the heat. My question is: somewhere on the internet I saw someone had made a tiny plastic piece to fit inside these adapters to make them work. Does anyone here remember this and/or know where I can get one?
