Dell docking station WD15 K17A on Framework 13 AMD - power delivery issues

I’m using a WD15 K17A on Framework 13 AMD.
It is announced to provide 90W of power delivery.
If i plug it on usb-c (port #1 or #3), everything works but power delivery fluctuates. Sometimes it works, sometimes it does not.
I can’t figure out any determinism yet.

Note: If I also plug the official framework power adpater, charging works

Do someone experience the same problem or have a lead for debugging ?


I think it’s best to get the EC log while this is going on and reporting it to framework support.

Have you update the BIOS to 3.05? The latest update fixed the PD negotiation problem on some power supplies
