MagSafe DC-In Board Problem after magsafe loos cable fix
Hi I have a Macbook Unibody A1278. My magsafe cable was loos, so I open the magsafe and fix it, unfortunately I solder the cables backward and plug it in to my macbook. After that the magsafe had a dim green light and the battery charge very slowly, I thought it was the MagSafe DC-In Board so I change it! when I did I was very happy, but my happiness only las 3 second, the magsafe bright green light went dim again! I bought a new battery as the one I had drain out of power and it was impossible to charge it again whit my computer! I have another MagSafe DC-In Board but I am afraid it will happen the same thing again! I believe it is a mother board issue but cant find any answers on the internet!
Is this a good question?
