How to use

Ensure the adapter’s voltage matches the laptop within ±0.5 V and that its power (W) and current (A) are equal to or greater than the laptop’s specified values. Attach the plug that matches the laptop’s DC jack (outer and inner diameters must match). Connect the adapter to the mains and then to the laptop; disconnect from mains when not in use.

Recommendations

Read the label on your laptop to confirm POWER, VOLTAGE and CURRENT values. Use an adapter with equal or higher W and A ratings and a matching plug size; maintain ventilation around the adapter to avoid overheating.
