USB-C charging faults on both ports
The M1 MacBook Pro 13 charges exclusively through its two Thunderbolt USB-C ports — there is no MagSafe on this generation. A machine that charges from only one side, shows 'plugged in, not charging', needs the cable held at a specific angle, or stopped charging after a knock or spill needs inspection. With only two ports, a single failed one removes half the machine's connectivity as well as half its charging paths. Test both ports with a known-good cable and adapter first.
