MacBook Pro & Thunderbolt Display
If I'm understanding this correctly:
7. Does the Thunderbolt port supply power to connected devices?
Yes. A Thunderbolt port supplies power if that Thunderbolt port is part of a device that is connected to an AC power outlet or is operating on battery power. If your Thunderbolt devices have their own power supplies, you should connect the power supplies to them for optimal functionality. If you are using Thunderbolt devices that get their power only from the Thunderbolt bus, computers running on battery power will experience battery drain more quickly.
So if the display is connected to a MacBook Pro power will be supplied BUT is a cable supplied (w/Display) for the Display connection to the MBP or does one have to purchase it separately?
