How to use

Confirm that the adapter's connector and voltage match the requirements of your Dell laptop before connecting.

When first powering the system, allow the battery to charge and the adapter to regulate output; avoid repeatedly connecting and disconnecting under heavy load. If the laptop does not indicate charging or the adapter becomes unusually hot, disconnect and inspect connections and compatibility.

Recommendations

Use the adapter on a flat, well-ventilated surface to prevent overheating and avoid covering the brick during operation. Store the adapter in a dry environment and avoid excessive bending of cables near the connector. Replace the adapter if casing is cracked, cables are frayed, or protection indicators show faults. Always verify connector polarity and fit before use.
