    I just bought a 13" MacBook Air, plugged in the MagSafe, and charged it fully. The question is should I drain the battery completely to 0% now and follow these instructions: Intel notebooks

    Intel notebooks, which includes all MacBooks and MacBook Pros, use the following method of calibration: [1]

    1. Plug in the power adapter and fully charge your laptop's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
    2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
    3. Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialogue on the screen.
    4. Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.
    5. Turn off the computer or allow it to sleep for five hours or more.
    6. Connect the power adapter and leave it connected until the battery is fully charged again.

    Or should I just not worry about it and use it normally? I don't know if I should drain it like I did when I first bought my 17" MacBook Pro.

    Do I really have to let the computer sleep for five hours or more? I might not wake up in time to be able to fully charge it and bring it with me to school tomorrow in the morning.
