How to use

Connect the adapter to an AC mains outlet using the supplied power cord, then insert the output plug firmly into the laptop’s power jack or docking station input. Ensure the laptop’s charging indicator shows active charging or that the docking station receives power. Use the adapter in a well-ventilated area and avoid covering the power brick during operation to prevent heat buildup. Unplug the adapter from mains when not in use or before moving the laptop to avoid stress on the connector.

Recommendations

Verify device compatibility by checking that your laptop or docking station requires 19.5V and accepts up to 7.7A input. Use only adapters with matching voltage and equal or higher current rating to avoid insufficient power delivery. Keep the adapter and cables away from liquids, extreme heat, and sharp bends; replace the adapter if the cable insulation or connector shows visible damage.
