65W AC Adapter for HP Pavilion and EliteBook

This 65W AC adapter delivers 18.5V at 3.5A for compatible HP Pavilion G4, G6, G7, M6, DM4, DV4, DV5, DV6, G60, G61, G72 and EliteBook 2540p, 2560p, 2570p, 2730p, 2740p models. It accepts a universal 100-240V input at 1.2A 50/60 Hz. The unit is brand new and intended as a direct replacement power supply for the listed laptops.

5.0mm by 7.4mm Smart-Pin Connector

The DC connector features a 5.0mm internal diameter and a 7.4mm external diameter with a central smart-pin. This specific geometry ensures the adapter communicates correctly with the laptop's power management system. Without the correct smart-pin interface, the laptop may refuse to charge or limit performance even if the voltage matches.

Straightforward Plug-In Installation

Installation requires connecting the AC cord to the adapter brick and inserting the DC plug firmly into the laptop's power jack until seated. The most common issue is a loose or worn DC jack on older laptops causing intermittent charging. Verify the connector dimensions match the original adapter exactly before purchase to avoid fitment problems.

Questions about this item

Will the 5.0 mm by 7.4 mm smart-pin connector wear out and need replacing?

The connector is a fixed part of the cable; if the pin or barrel becomes loose or damaged the entire adapter must be replaced.

What limits continuous operation at the full 65 W output?

The adapter is rated for 18.5 V at 3.5 A; sustained loads at that level will reach its thermal design limit first.

How hot or loud does the 100-240 V 1.2 A input unit get when running all day?

It is a sealed, fanless brick; under constant load it warms to a typical external temperature but produces no audible noise.
