If it's not okay, then I'm seriously screwed. I've had a number of PowerBooks and iBooks left plugged in and on/sleeping 24/7 since 2001.I would imagine that the battery's microcontroller stops the energy flow once it arrives to a 100% so the battery does not die. Is this true?
Apple said:For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing.
