In a botched repair job on my MBP's power adapter, the positive and negative wires got reversed. Alas, when I connected it to my MBP, it died. I could smell a minute amount of burning coming from the DC jack on the MBP. In time, I was able to follow these instructions to replace the DC jack. However, though the procedure was followed successfully and the power adapter's polarity was corrected and connected to the MBP, the MBP is still dead. No lights. Nothing. What else, besides the DC jack, would probably be fried? Thanks!
