Question about HP 1pm64aa

Hi, so the docking station works with the Surface Pro 7. It also supplies power via USB-C.

Yes, but for full functionality the driver should be downloaded and installed from the HP support site.

Good day

Is used for a HP Probook 430 and works perfectly.
Regarding the Surface Pro 9 I can not make a statement

I can't help you there. We have it running on an HP 440 and it works wonderfully.
