Problem with MacBook Internal Power Connector

One of our readers from a certified Apple Repair Center sent us a report concerning a problem affecting the internal power connector of some MacBooks.

As shown on the photo, there is a short circuit between the internal connector and the motherboard. It burns tracks, and the entire board has to be exchanged.
The problem does not affect many units (yet?), but we can confirm from our disassembling experiments, that the internal connector seems lousy, while it is a critical component.
Another member from an Apple Repair Center confirmed the initial report. So we can suspect that the recent modification of the MacBook motherboard as we reported previously might not only be to support EnergyStar regulations but mostly to upgrade the internal power connector. In addition, we have learned that Apple is sending a need internal power connector with all new motherboard.
