65 W AC adapter for HP Pavilion and Compaq

This 65 W AC adapter supplies 18.5 V at 3.5 A to a wide range of HP Pavilion and Compaq notebooks. It replaces part numbers such as 9155068, 393954001 and 394224001. The package includes the adapter and a detachable power cord.

Thermal and electrical behaviour

The unit accepts 100–240 V input at 50–60 Hz and delivers a steady 65 W output. Built-in overload, over-voltage and short-circuit protection limit heat and noise during normal operation. No active cooling is fitted, so the adapter runs silently.

Upgrade context and fit

It suits owners of compatible Pavilion DV, TX, DM and Mini series laptops plus Compaq Presario and Folio models that require the 4.8 mm × 1.7 mm barrel connector. Buyers whose devices need a different voltage, current or connector size cannot use this adapter.

Questions about this item

How do I install the 18.5V 3.5A 65W adapter and what step is often missed?

Plug the 4.8mm×1.7mm connector firmly into the laptop's DC jack, connect the three-plug power cord to the adapter's inlet, then plug the cord into a 100-240V 50-60Hz wall outlet; the step often missed is verifying the connector size matches the original before powering on.

What maintenance or replacement will the 65W AC adapter need later?

The adapter has no user-serviceable parts; keep the three-plug inlet and 4.8mm×1.7mm connector free of dust, avoid cable strain, and replace the unit if output drops below 18.5V 3.5A or the built-in overload, over-voltage and short-circuit protection trips repeatedly.

What limit appears first on the 18.5V 3.5A charger under sustained load?

Continuous operation at the full 65W rating will eventually trigger the internal thermal protection, causing the adapter to shut down until it cools; this thermal limit is the first constraint reached during prolonged maximum-load use.
