Hey @pkunk,
Did you have the same issue with your 11th Gen i5 board? Do you have another charger to test out the ports with?
I already tried another charger. To refresh my memory, I tried operating my 11th Gen Mainboard standalone, and I can confirm that it runs from both USB-C ports on the right side.
For the BIOS comment, I would’ve done a support ticket, if not for my next discovery.
The standalone motherboard idea for the Ultra series was good. After testing (involving unplugging the battery), I noticed that the lights came on, even with the use of a USB-C card.
After replugging the battery, the right side appeared to have magically started working. I still have no idea why data was working earlier but not power, though.
I guess the issue is solved, and the moral of the story is to replug the battery multiple times and to not rely on battery disconnect through the BIOS.
