MacBook Pro '11 stops charging as soon as you start exporting video from iMovie. A video demonstration in the link explains the phenomena.

The video demonstrates the issue, but does not explain it. Do you have a question? The implication is that there's something wrong, but what you're seeing is normal. Under heavy processor loads (video rendering is among the most processor-intensive tasks), the computer can require more power than the AC source can provide. When that happens, the computer will also draw power from the battery. At those times, current is flowing out of the battery, not in, so the status updates to Not Charging to reflect that fact.

Please stop misinforming people - this issue is widely documented and unaddressed with ANY type of actual solution in an 11 page thread on this topic.

Apple will not replace your machine for this reason as it is described as "expected behavior" for your machine to require battery power while plugged into the wall.
