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.
