New HP USB-C Dock G4

I cannot seem to get the Thunderbolt working on this machine  

I have 

1) used 3 other devices to attempt to charge (1 Dell port replicator, 1 Dell usb-c dedicated charger and 1 Off brand port replicator) 

2) On the advice of support sent in my laptop to HP to have it 'repaired' (took a month got it returned and it would still not charge via usb-c)

3) once it still did not work was told that those devices were the actual problem (as they were not 'compatible') not the hardware that was replaced (ugh) advised to get one of several HP docking statins of which the USB-C Dock G4 above was included. and this one does not work either

Anyone know how one gets the Tunderbolt charging working on this machine??

The USB-C G4 dock is compatible with the following deries

• HP ProBook 600 G4, 400 G5, G6
• HP EliteBook 800 G5, 700 G5
• HP EliteBook x360 1030 G6 & 1020 G2, G3, G4
• HP EliteBook 1040 G4
• ChromeBook x360
• HP Elite x2 1012 G2
• HP Elite x2 1013 G3, G4
• HP Pro x2 612 G2
• HP ChromeBook 13
• HP Spectre Pro 13 G1 Notebook PC
• HP EliteBook Folio G1; HP Elite x2 1012 G1

The zBook 15 G5 machines are compatible with the following docks

• HP Thunderbolt Dock 230W G2
• HP ZBook Dock with Thunderbolt 3

One BASIC reason why the dock won't charge your machine is your machine needs 150W charger and the USB-C g4 dock can't supply that much power.
