Primary (Power) USB-C seems damaged
The port works for the most part, but occasionally charging on that port while using the machine, I get kernel panics and the machine crashes leading me to believe the port or some trace to the port is bad. The other port seems to function just fine. But my question is the port replaceable or is it hardware coded like Apple seems to love doing to their parts?
IE can I buy and solder a new port on (assuming it is the port) and be good to go, or would I need some kind of coding tool from lenovo?
Is this a good question?

@wukong7a72642c have you checked the Kernel error to see what that is pointing to? What is the exact motherboard in your Lenovo ThinkPad T14 Gen 1 (I would expect a NM-C931or a C791)? Also, which port are you considering your primary port?

@oldturkey03 THat is the neat part, there isn't one. The effect is that an event happens with USB, which is recorded but immediately stops all power (even on battery) and halts the machine and reboots. There were hints of power irregularity when windows was shipped on the device too, but in less obvious ways. IE boost being halted because the machine thought the Official 65w power brick was not supplying correct power. power brick has been replaced by lenovo and still occurs only on the suspected bad port, and EC warning sometimes persist. moving power to second port does not display any of this odd behavior.
Still operates fine, as a data port, although admittedly I don't trust it at all. The likely damaged port is the upper most USB-C port, the one that looks like it is bundled in what looks like a dock connector port works fine with none of this behavior.
