Questions about this item

Will this 18.5 V 3.5 A adapter run a Compaq Presario X1428ap alongside the original battery?

Yes, the 65 W output matches the laptop's requirement and the 1.7 mm by 4.8 mm connector fits the X1428ap, X1429ap and X1431ap models, so the adapter charges the battery while the system runs.

How can I confirm the adapter is delivering the correct 18.5 V after I plug it in?

The LED on the adapter body lights when mains power is present; you can also verify 18.5 V at the DC plug with a multimeter or watch the laptop's charging indicator show active charging.
