Replacement charger for HP part numbers

This 19V 1.58A 30W AC adapter replaces HP chargers NE579PA, NE580PA, NE581PA, NE581PAR, NE582PA, NE585PA and NE590PA. It accepts 100 to 240V AC input at 50 to 60Hz and delivers 19V DC at 1.58A. The barrel connector measures 4.0mm by 1.7mm. A country-specific power cord is included in the box.

Bundled power cord covers local mains

The package supplies one AC adapter and one power cord with a US, UK, EU or AU plug that matches your mains socket. No separate cable purchase is required and no software or driver installation is involved. The 24-month warranty covers the adapter and cord together. Buyers who need a higher-wattage unit or a different connector size cannot use this model.

Straightforward swap with polarity check

Installation consists of unplugging the old brick, connecting the new adapter to the laptop and attaching the supplied cord to the wall. The only common issue is reversing the centre-positive polarity or selecting a cord with the wrong regional plug. Verify the 4.0mm by 1.7mm tip matches the laptop socket before powering on.

Questions about this item

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

The 4.0mm*1.7mm barrel connector is a standard passive part with no moving contacts; it only needs replacement if the tip is physically damaged or the cable sheath frays.

What limits continuous use of the 30W 19V 1.58A output?

The adapter is rated for a steady 30W DC output at 19V 1.58A; sustained loads above that rating will trigger its internal protection and shut the unit down.

How much heat or fan noise does the 100-240V 50-60Hz input produce when running all day?

The unit has no fan and relies on passive convection; under normal 30W load it becomes warm to the touch but remains silent during all-day operation.
