Hi @nachokingp ,
Both the USB-C ports are hard mounted on the systemboard, so you will need smd soldering skills and tools to replace them.
Visually inspect the ports, using a strong light and a magnifying glass to check if you can spot a problem either with the pins or the port enclosure.
If there appears to be dust or lint etc in the enclosure, that may be preventing a good electrical connection, do not use a metal pin or probe to try and extract it, use a vacuum cleaner instead to try and suck it out.
Here’s the hardware maintenance manual for the laptop. Go to p.46 to view the necessary pre-requisite steps and then the procedure to remove the systemboard as this will need to be done to replace the connectors.
If doing all this seems too daunting, contact a reputable. professional laptop repair service and ask for a quote.
