How can I correctly calibrate the battery of the Late 2010 MacBook Air battery? The Apple support site says that I should use the laptop until it turns off by itself, and then I should shut it down before charging it. But how can I turn it off when I cannot turn the MacBook Air back on to turn it off during critical battery levels? I don't want to wait 5 hours before the battery is totally drained during sleep before I can charge it.

Run the computer until it turns itself off. I would wait another 20 mins or so to ensure the battery is cool, plug in the charger and allow to fully charge until its at 100% before removing the charger.

I don't think it turns itself off. One time it was playing a video and the battery went flat. The screen went out but the audio kept going until I plug the power in, waked the laptop and paused the video.

^ Correct. You have to discharge the battery to the point of forcing the laptop to sleep, then leaving it uncharged for at least 5 hours to run down the battery completely. Then you charge it fully.
