Will it charge the laptop's battery if the laptop is shutdown?

I understand that it doesn't provide enough power to both power the laptop and charge the battery simultaneously. But it would seem that if you do not have the laptop powered up, then there might be enough power to charge the battery.

  • it will not, it is only to give workable power to the computer, not the battery.

    No. It will not charge the batter as the MacBook and MacBook Pro detects whether its a power supply or this cord.
