19V 30W AC adapter for HP 1010NR

This 19V 1.58A 30W AC adapter is built for HP 1010NR series laptops. It accepts 100 to 240V AC input at 50 or 60Hz and delivers 19V DC at 1.58A. The 4.0mm by 1.7mm connector matches the original charging port. A region-specific power cord is included in the box.

Thermals noise and power draw

The adapter runs at 30W output with a standard 24-month warranty period. In normal use it draws power only when the laptop is charging or running on mains. No active cooling fan is present so operation is silent. The external casing dissipates heat passively during typical office workloads.

Sustained load behaviour

Under continuous load the unit maintains 19V 1.58A output within its 30W rating. The 100 to 240V input range handles voltage fluctuations without shutdown. Passive thermal management keeps the housing warm but within safe limits during extended charging sessions. The 24-month warranty covers defects in materials and workmanship.

Questions about this item

How do I connect the 4.0mm*1.7mm barrel plug to my HP 1010NR without damaging the port?

Align the 4.0mm outer and 1.7mm inner diameters straight with the laptop jack, push gently until fully seated, and route the cord so the connector is not bent sideways.

Which part of this adapter will wear out first and need replacing?

The detachable power cord and the barrel connector see the most physical stress; the adapter body itself has no user-serviceable parts and is covered for 24 months.

At what point does the 30W output limit throttle my HP 1010NR during heavy workloads?

When the laptop tries to draw more than 30W (19V × 1.58A), the adapter cannot supply the extra current and the system will reduce performance to stay within that ceiling.
