If your USB-C power adapter isn't charging your Mac laptop
Only first the USB-C ports , the one closest to the screen, is not charging my Macbook Air.
The second USB-C port is working fine and is charging my Macbook Air.
Problem is only with the first port.
I have:
- cleaned with canned air
- cleaned charger contacts
- done a hard shut down
- Quick restart: click the Start menu > Power button > Restart. On a Mac, click Apple > Restart.
