Dell wd19 not connecting to HP Probook G5

[ondrejzverina]

Hello,

I have recently bought Dell WD19. Right now it only works when I connect my normal charger too and if i disconnect it after it still works. But when I connect just the dock, the led which is on the usb-c connector seems to charge some capacitor, then blinks, which can be seen just in dark and some noise from the discharging can be heard too. It is something like clock ticking. 

Thanks

Very simple: they are NOT compatible. If you wish to use dock, please use the following list (read the last few pages first):

I don't think that's the only answer to that problem. Because otherwise It wouldn't work at all.
