How to use

Connect the adapter to an appropriate AC mains outlet using the supplied AC lead, then plug the DC connector into the power inlet of the HP portable device. Ensure the connector is fully seated and that the device accepts the adapter; the Smart RC functionality should permit the host system to detect the adapter and apply correct charging logic.
