I've had 3 Magsafe connectors fail on my 1st gen MBP
- First, the cable frayed. I thought it was faulty design (since it also happened on another MBP we bought at the same time), but it could have been my fault. Apple, in their wisdom, don't put any serrated "grips" on their plugs making them harder to pull out. So, I was leveraging the magsafe connector off by putting my finger under the cable and levering it up and off. Over time, this seem to have frayed the cable.
Edit: ignore the above. After reading the KB article, it sounds like exactly what I experienced. The cable was discoloured where it was 'bending'.
- The second melted through the cable insulation, at the Magsafe end.
- The third, the other end (wall socket piece of the cable) failed. This also happened with a colleague's MBP.
- As I speak, the light in my newest power adaptor is flickering from green, to orange, to green... Hope that's not a sign of problems to come...
Even though I've already replaced it, I wouldn't mind a free replacement in case this one fails. Pity there isn't an Apple Store in the country.
