Which chargers work

The manufacturer states no minimum USB-C charger wattage for this model. A charger rated below the 140 W it lists may charge more slowly, or may not keep up when the laptop is under heavy load. The manufacturer's manual is the authority on what a lower-wattage charger does.
Worth knowing before you buy
- A charger with high advertised wattage but no USB Power Delivery support may not charge this laptop at all — wattage alone doesn't determine compatibility.
