When calibrating your battery, after you have done the discharge and your computer is asleep, does it matter if you plug in for charging up to full AND use your computer while charging? Or are you supposed to let it sleep until it's fully charged?

According to this (http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh1959.html) article in the Apple KB, I don't think it matters if you are using it - which it really shouldn't. Surf away!

The article doesn't really say... I suppose that might mean it doesn't matter. I can't see that it should matter, either, but I'm not sure whether the battery will draw the same amount of current asleep as awake (which is I guess what the real question is).

Emw is right it doesn't matter. :)

I don't think current draw is the issue. If you really wanted to minimize draw, then shut down. Essentially, the idea is to tell the battery how much it can hold. Running it until it sleeps tells it how low it can go, and charging it back up tells it how much it can hold.
