Charge thresholds, temperature, an underpowered USB-C adapter, damaged cable/port or battery condition can all pause charging. Verify power rating and firmware status first. Compare the charger's wattage with the laptop's rating and try the original adapter. Look in the manufacturer's power app or BIOS for a charge threshold or limit.
