How to use

Connect the adapter to AC mains using the supplied mains lead, then insert the output connector into the laptop or docking device power inlet until it seats securely. Ensure the device is powered off or in a low-power state when first connecting, if possible. Monitor the device for normal charging indicators such as LED status lights or on-screen battery icons. Disconnect the adapter by removing the output connector first and then unplugging the mains lead from the wall outlet. Allow the adapter to cool before storing.

Recommendations

Use the adapter with devices that explicitly support a 19.5V / 3.34A power input and up to 90W power draw. Avoid using adapters with incompatible voltage or connector types. Do not expose the adapter to moisture, extreme temperatures, or heavy physical stress. If the adapter becomes unusually hot, noisy, or emits odors, discontinue use and inspect the adapter and device for faults. For best results, pair the adapter with devices and docking solutions specified by the laptop manufacturer to ensure safe and reliable operation.
