Ensuring Sufficient Power for Your Computer
Your computer is designed to use a 65-W or 90-W AC adapter. However, for optimum system performance, you should always use a 90-W adapter.
Using less-powerful AC adapters, including the 65-W AC adapter, 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

AC Power Loss While the Computer Is Docked
If a computer loses AC power while docked to the Dell D/Dock or Dell D/Port, the computer immediately goes into low-performance mode.
