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.
