Latitude 5420

Full Compatibility means the docking station is fully compatible with the laptop, including display output, ports, power supply, and advanced features like Power Sync and MAC Address Pass Through. Partial Compatibility means the docking station is still usable with basic display output and ports functional, but there may be limitations such as insufficient power supply for the laptop's requirements, or unavailable features like Power Button Sync.

1. Higher compatibility and more stable operation with same-brand docking stations. 2. Certain advanced features, such as Power Button Sync and MAC Address Pass Through, may only work when paired with laptops from the same brand. 3. Manufacturers may implement proprietary protocols that enable higher charging performance and data transfer rates with same-brand docking stations.

The docking station's display and USB ports may still function, but the laptop will display a power insufficient warning, leading to reduced performance. To achieve optimal performance, the laptop may need to be connected to an additional power source.
