I've been using a Dell Precision 7510 for work with a TB16 dock that was recently replaced with a Precision 7560.  My TB16 dock had a 240W power supply for it to power the 7510. When I plug in the 7560 into the TB16 via the USBC it says that it is charging but it isn't optimal.

Since the old laptop worked without any issue and the power supply on the TB16 is more than adequate, as well as a higher wattage than the power cable that came with the 7560, why doesn't the TB16 generate the necessary power for the 7560?  From what I've found in reading it looks like there is a newer TB model that seems more compatible with the 7560, is this more of a case of planned obsoleteness for the TB16 for the new laptop or is just not fully compatible with the 7560?
