Steps
Power the laptop off, unplug the charger and remove the bottom cover screws. Lift the base panel away and keep the screws in a tray.
Unplug the internal battery connector from the motherboard first. This keeps the board dead while you heat and solder the USB-C ports.
Disconnect the ribbon cables, speaker and antenna leads, then remove the fan and heat pipe. Lift the motherboard out of the chassis.
Put the board under a microscope. Add flux and low melt solder to the pins of the old USB-C connector so the joint flows at a lower temperature.
Warm the connector with a hot air station at about 400°C and low airflow. Lift it straight up with tweezers once the solder turns shiny.
Clean the pads with a soldering iron and solder wick, then scrub the area with isopropyl alcohol and let it dry completely.
Line the new USB-C connector up on the pads. Tack two opposite corners with a fine iron tip, then solder the remaining pins.
Check every pin under the microscope for bridges. Test each pad with a multimeter in continuity mode before you refit the board.
Refit the motherboard, reconnect the fan, cables and battery, and fit the bottom cover. Plug in the charger and test charging and data on both ports.
Tips and common mistakes
Try cleaning the port with isopropyl alcohol and a soft brush first, since lint is often the real cause of a bad connection.
Keep the hot air nozzle moving and never pull a connector while the solder is solid, or you will rip pads off the board.
Practice on a scrap board first, because the pads on a thin laptop board lift very easily.
A hot air station, soldering iron and lithium battery all carry burn and fire risk, so work in a ventilated space with the battery unplugged.
Questions
Do I need a microscope for this repair?
For a clean result, yes. The pins are tiny, and you need magnification to spot solder bridges and lifted pads before you power the board up.
Can I replace only one USB-C port?
Yes. If one port is dead you can swap just that connector, but check the second port too since it has seen the same wear.
What if the laptop will not charge after the repair?
Recheck the pins for bridges and confirm the battery connector is fully seated. One shorted pin can stop the board from powering on at all.
