Disconnect the DC connector by pulling the plug, not the cable, and store the adapter in a dry, ventilated place when not in use.

Recommendations

Use this adapter only with laptops that specify 19.5V and a compatible current rating. Avoid operating the adapter in excessively hot, humid or dusty environments and prevent cable strain by routing cords without sharp bends. If the adapter becomes unusually hot, emits odors or shows visible damage, discontinue use and replace it. For battery health, avoid keeping the laptop continuously at 100% charge for prolonged periods if not needed.
