The dock charges the laptop but the monitors stay dark - why?

On a DisplayLink dock, install the DisplayLink driver - external screens over USB do not work without it. On a Thunderbolt dock, check that the device is approved in the Thunderbolt settings.

Windows sees the dock but some ports are dead - what may help?

Update the dock maker's package and the dock's firmware - large vendors ship both as separate downloads in the model's support section.

Will another brand's dock work with my laptop?

Technically often yes - USB-C and Thunderbolt are standards. Brand-specific extras like charge management are more reliable in matching pairs.

About docks & port replicators drivers

The classic dock complaint: the laptop charges, the monitors through the dock stay dark. On DisplayLink docks external screens run on a separate driver - without it there will be no video, however many times the cables are reseated. On Thunderbolt docks the usual suspects are the dock's firmware and the Thunderbolt approval settings.

Updates work best as a pair: the DisplayLink driver plus the dock maker's package (HP, Dell and Lenovo ship their own) - they complement each other.
