Laptop won't charge — check the USB-C port first
TL;DR: Inspect the USB-C port for lint, bent pins, or a loose connector before assuming the battery is dead.
What to try
- Try a known-good charger and cable (USB-C PD, correct wattage).
- Look inside the port with a bright light — pocket lint is the #1 cause.
- Gently wiggle the plug: if charging only works at an angle, the port may be worn.
Safety / when to stop
Do not poke metal into the port. If the port is physically broken or the board smells burnt, stop and book a repair.
