There's still one unclear point that I hesitate in buying this dock, maybe the community can help: my non-HP laptop has a USBC 3.2 Gen 2 full function (PD 3.0, DP 1.4) which is currently used to connect its 140W charger (I guess it uses another circuit negotiation but not using PD mode though). When this dock is connected to the laptop via its TB4 (another laptop's port) while the laptop's charger is not connected, the dock will provide 100W max. Will this be sufficient for the laptop as it has internally PD 3.0 (meaning max. 100W) or insufficient because its charger requires 140W? Many articles mentioned that it is not good to charge a laptop with a charger having a wattage lower than the laptop's charger! The question is: it is possible to use this dock while skipping laptop's charger? Or should we use both? Thanks!

Answer

Update: IT SEEMS THAT IS NOT A TB4! Following the answer of Schachtler, I have bought this. Connected to laptop's TB4 port (laptop Lenovo new generation, 3 months old) -> Nothing works, as if the dock is not TB4: No ethernet LAN, no external USB devices (SSD HDD), no signal to DP monitor, no signal to HDMI monitor, and the laptop (140W) complains that the power is lower than it requires! I wonder where is the problem!
