Alright, I was confused on my CD MacBook at first too but after skimming over the article a couple times I understand it now, here's what you do.
- Charge the machine until the MagSafe connector is green, you can use the computer while this is happening.
- Leave the battery fully charged for at least two hours, you can use the computer during this time as well.
- Disconnect the MagSafe connector and use the computer until it shuts off meaning you've drained your battery and the machine has put itself to sleep.
- Allow the machine to stay asleep for 5 hours or more (usually overnight I recommend). Do NOT reattach the MagSafe during this time.
- After the 5+ hours (or the next morning) plug the MagSafe back into the machine and connected until the battery is fully charged again.
Hope that helped.
Edit:
PS : Calibration is basically using the battery till the end then racharging it right?What exactly is the point?I've read you shouldn't really calibrate it often.
You're right. I usually do it every month or two months, I forgot which but I have an iCal alarm to remind me to do it.
