How to use

Confirm that your notebook requires a 19V input and accepts a 3.0×1.1 mm DC plug before connecting. With the device powered off or in a low-power state, insert the 3.0×1.1 mm plug into the laptop power jack until it seats securely, then connect the charger to an appropriate AC mains outlet. Monitor charging status via the laptop indicator light or operating system battery icon. Disconnect the adapter from the mains before removing the plug from the notebook.

Recommendations

Use the charger in dry, well-ventilated locations and avoid covering the adapter while in use to prevent heat buildup. Verify polarity and plug compatibility prior to use. If the laptop does not charge or shows unusual behavior, stop using the adapter and consult a technician or the device manufacturer.
