Q: Please help! 17" Macbook Pro - USB Stops Working
I have a 2010 edition Macbook Pro 17" and I am facing a strange issue that is really damaging to me. I am a DJ and use this machine for work, and it has been failing me.
Simply put - when I plug this Macbook into an 85w adapter, I get noise in my headphones and my USB ports stop working intermittently. It causes my DJ controller to disappear and reappear constantly in the Sound settings in System Preferences, and makes it so I cannot play and music. If I unplug the 85w adapter however, everything works fine and I get no noise in my headphones. I've called my local shops and they have never seen this issue, with one shop saying it may need a new controller card for $500.
Can someone please give me some clue as to what I could do to fix this? I've tried resetting SMC but no dice.
MacBook Pro, OS X El Capitan (10.11.6), 2010 edition 17"

It is a possibility that the adapter is the culprit and if so, it will be the least expensive solution. Consider making an Apple store genius bar appointment for a FREE evaluation.
Ciao.
