How to use

Verify that your laptop accepts a 19 V, 3.16 A adapter and that the connector tip matches your device before connecting. Plug the adapter into a compatible AC mains outlet, then insert the DC connector into the laptop power inlet until it seats securely. Ensure proper ventilation around the adapter during use and avoid covering it with fabrics or other materials that may trap heat. Disconnect from the mains and the laptop when not in use or during prolonged inactivity.

Usage recommendations

Confirm polarity and plug dimensions against the original adapter or laptop documentation. Use the adapter indoors on a stable, dry surface and avoid exposing it to moisture or extreme temperatures. If the adapter becomes unusually hot, emits odors, or shows visible damage, discontinue use and replace it to prevent potential damage to the laptop.
