The Dell Universal Dock D6000 series has a dual-configuration USB cable connection. It ships configured for USB Type-A connections. (Figure 1)

The Dell Universal Dock D6000 series can provide Dell computers with 65 W power using a USB Type-C port (Figure 2) configured for charging when docked to the computer.

The Dell Universal Dock D6000 series may not charge some docked computers in some configurations. This is due to either a limitation of the cable connection that is used to dock the computer (Figure 1) or a limitation of the computer that is connected to the dock.
Computers docked using USB 3.0 Type-A connections (Figure 1) or computers that require more than 65 W of power input to power the computer and charge the battery require a separate AC power adapter to power the computer and charge the battery.
The dock is designed for these computers but requires the computer AC adapter for computer power.
The dock is designed for these computers and is documented to have USB Type-C ports that are configured with the ability to charge the computer using the computer to dock USB connection. (Figure 2)
For computers requiring over 65 W, an additional AC adapter may be required for optimal performance. Check your AC adapter for power requirements. The battery does not charge when connected using only a USB 3.0 Type-A (Figure 1) connection to the dock. This is because power delivery is only through Type-C (Figure 2). When using the Type-A connection, then you must connect the computer AC adapter to power the computer and charge the computer battery.
