How to use

Connect the adapter to an appropriate AC mains outlet using the supplied mains lead or a compatible regional power cord. Plug the DC output connector into the laptop power inlet until it seats securely. Ensure the laptop model accepts a 90W adapter and the connector matches before use. Observe the device charging indicator to confirm power delivery. Disconnect from mains and the laptop before performing any hardware maintenance or when transporting the adapter to avoid strain on the cable and connector.

Recommendations

Use the adapter in a well-ventilated area and avoid covering the adapter housing during operation to prevent overheating. Verify voltage compatibility with local mains supply and use the correct regional power cord. Replace the adapter if the cable shows visible damage, fraying, or if the connector becomes loose. For prolonged high-load operation, allow periodic cooling intervals to maintain optimal performance.
