Hello, 

if I plug my Dell power adapter to one of the 3 usb-c ports, I get an error message:"PC isn't charging. Use the recommended charger and cable, and make sure it's directly plugged in."

I already opened a ticket, the issue didn't repeat for few days after updating the BIOS, but uius now back. Hardware diagnostics report no problems. Windows, BIOS and drivers all updated.

Could you please help?
