I just took a transatlantic flight on a newish 777 that had AC power at the seat. My MBP 15" unibody behaved strangely. The Magsafe connector turned green as usual, and the MBP indicated: "charging" but the mouse (built in pad) became all jumpy, it was imposible to control, and the connection introduced noise on my headphones. Unplugging the Magsafe from the MBP restored mouse control and stopped sound interferance, The AC charged my iPhone (smaller AC adapter just fine). I tried: 1) A second AC plug in another seat - same issue 2) A second AC adapter (I travel with two) Same issues remained. Another passenger had a MB Air and had no problem. Other passengers had PCs of various sizes with no problems. I know the MBP adapter draws more power, but it is a standard AC 110v plug and it seemed to be the only machine with the issue. No one seemed to have another MBP in the cabin so I could ask. I decided not to continue with the AC plugged in - just in case. Upon arrival it has worked just fine in several Hotels. Anyone experienced this issue on an Airplane?
