65W 18.5V AC adapter for HP Pavilion DV4100

This 65 watt power supply delivers 18.5 volts at 3.5 amps to charge compatible HP Pavilion DV4100 series laptops.

An AC power cord is included in the box.

Thermals noise and power draw

The adapter operates at its rated 65 watt output during normal charging cycles. Heat generation remains typical for a unit of this power class under standard load. No moving parts are present, so the unit runs silently without fan noise. Power draw from the wall matches the 65 watt DC output plus normal conversion efficiency losses.

Questions about this item

How do I install the adapter and which connector detail is most often overlooked?

Match the 18.5V 3.5A rating to the laptop, plug the barrel with 1.7 mm inner and 4.8 mm outer diameter firmly into the DV4100 jack, then connect the supplied AC cord to a 100–240V 50–60Hz outlet.

What part will need replacement first and how can I delay it?

The AC cord and barrel tip wear first; avoid sharp bends near the connector, unplug by the plug body not the cable, and keep the brick ventilated so the 65W output stays cool.
