This is normal. The batteries used in these computers are designed to avoid short discharge/charge cycles in order to prolong the overall life of the battery. Because of this, when setting the Mac OS X battery status menu bar icon to display charge state by percentage, you may notice that the reported charge stays between 93 or 95 percent and 99 percent. When the battery level eventually drops below 93 or 95 percent, it will charge all the way to 100 percent.

As to why it did that from 40%, who knows.. but I wouldn't worry about it. Use it until you hit the 90% mark and plug the charger back in, and see if it hits 100%.

let us know.
