AIUI the Fw13 Intel versions all had problems with increased current draw when the USB A port expander was fitted. Someone had a thread on here where they were modifying them with a microswitch so that when a device was plugged into the port it operated a microswitch that notified the USB-C port that it now had a device fitted. The native USB A port expander had a wire that caused the USB-C port to think there was an active device plugged in all the time.
