I am having expansion port problems on my new Framework 13 Ryzen (it arrived earlier this week):

  1. Port #3 (upper right) won’t power/charge the computer. The other three do, I have swapped the USB-C expansion module with a “working” one, and the problem stayed on port #3. I have tried two different USB-C power supplies, neither can power/charge on port #3.

    (How I know: the display dims to save power, the UI tells me I am on battery power, and after a few minutes I see the charge level falling; plug the power supply into another expansion port, and it charges.)

  2. An external portable monitor works on two of the ports. #1 (top left) and #4 (bottom right). #2 gives me UCSI_GET_PDOS failed (-5) in syslog and the display’s power LED blinks. #3 gives me nothing in syslog and the power LED stays dark.

    (The external monitor is an ASUS MB169 manual doing Display Port Alt Mode over USB-C. It works with my old Intel Dell XPS 13; in the past it has worked with a Macintosh and a Lenovo.)

Suggestions?

Thanks,

Nothing to add particularly, other than this has been consistent with my experience and many others. I have a completely unusable lower left port, a sometimes working lower right port. Only the left and right upper ports seem mostly consistent. (Although the right one often goes into a state where plug/unplug of display/docks stops working until a reboot).

Not everyone seems to experience this tho. But there is obviously some commonality/defect for a percentage of units.

Nasty.

Buy a machine with 4 ports because only a couple are sure to work?
