How to use

Confirm that your laptop requires 19 V DC and can accept a 5.5x3.0 mm barrel plug before connecting. Connect the adapter to the mains supply using the supplied AC lead or a matching regional mains cord, then insert the DC plug into the laptop's power inlet until it seats firmly. Observe device charging indicators and allow the laptop to charge or operate normally. Disconnect the mains supply and unplug the DC connector when the adapter is not in use or before moving the laptop to avoid strain on the connector.

Usage recommendations

Use the adapter in well-ventilated areas and avoid covering the adapter brick during operation to ensure proper heat dissipation. Verify polarity compatibility and voltage requirements for your laptop model; using an incompatible adapter can damage the device. Store the adapter and cables coiled loosely to prevent cable fatigue and inspect connectors periodically for wear or damage.
