Ensuring Sufficient Power for Your Computer Your computer is designed to use a 65-W or higher AC adapter. Using AC adapters that are less-powerful than 65 W will cause you to receive a WARNING message. Docking Power Considerations Due to the extra power consumption when a computer is docked to the Dell D/Dock, normal computer operation is not possible on battery power alone. Ensure that the AC adapter is connected to your computer when the computer is docked to the Dell D/Dock. Docking While the Computer Is Running If a computer is connected to the Dell D/Dock or Dell D/Port while the computer is running, presence of the docking device is ignored until the AC adapter is connected to the computer.
