Compatible HP Part Numbers

This 30 W AC adapter matches HP part numbers NE576PA, NE577PA, NE578PA and NE579PA. It delivers 19 V at 1.58 A from a 100–240 V, 50–60 Hz mains supply. The 4.0 mm by 1.7 mm barrel connector fits the listed models directly.

Included Power Cord

The package supplies the adapter and a detachable mains cord with a US, UK, EU or AU plug that matches the destination country. Having the correct cord removes the need for a separate travel adapter. Buyers whose laptop uses a different barrel size or voltage will need a different unit.

30 W Output Limit

The adapter is rated for 30 W maximum output, so it cannot power laptops that require higher wattage. The fixed 19 V output suits only devices designed for that voltage. Users needing more current or a different connector must select another model.

Questions about this item

Will the 4.0 mm × 1.7 mm barrel connector wear out and need replacing?

The connector is a standard 4.0 mm × 1.7 mm barrel; it does not have a rated cycle count, so treat it as a non-user-replaceable part and replace the whole adapter if it becomes loose.

What limit appears first when the adapter runs continuously at 30 W?

The hard limit is the 30 W (19 V × 1.58 A) DC output rating; sustained loads above that will trigger overload protection or cause voltage to drop.

How much heat and noise does the 30 W brick produce when left on all day?

It is a fanless 30 W unit with 100–240 V 50–60 Hz input, so it runs silently and reaches only warm temperatures under normal continuous load.
