A week ago, I noticed my charger was not charging my laptop. I took it in to the genius bar, and they tried a different charger, and it worked great. At that point, i also mentioned a pixel issue I had on the screen, so they took it in for 3 days. I picked up the laptop and got home, connected it to charge, and after about 10 minutes, again i see the dimmed green light when its not even charged. I then turned the magsafe charger around so the wire is facing me, and it works great. What can I do now? I am upset, they didn't take the chance to even check that it was really the charger while it was there for 3 days... Anyone had this symptom? If so, what did you do?
