Replacement AC adapter for HP notebooks

This 65 W adapter supplies 18.5 V at 3.5 A through a 4.8 mm × 1.7 mm barrel connector and a three-prong mains cord. It is designed for owners of compatible HP Pavilion DV and Compaq Presario series notebooks who need a new power supply.

Thermals noise and power draw

The unit accepts 100-240 V at 50-60 Hz and delivers a steady 65 W output for normal charging and operation. No active cooling is present so the adapter runs silently while the external casing dissipates heat during typical use.

Build fit and requirements

A standard IEC C13 mains cable is included for immediate connection to a wall outlet. The barrel tip matches the 4.8 mm × 1.7 mm jack found on the listed HP models and the adapter does not require any additional drivers or proprietary docking hardware.

Questions about this item

How do I install the 4.8 mm × 1.7 mm barrel connector without damaging the laptop's DC jack?

Align the centre pin with the jack's socket, push straight in until it seats firmly, and avoid angling the plug — side pressure bends the delicate inner contact.

Will the detachable 3-prong IEC power cord need replacement over time?

The cord is a standard C13 lead; replace it only if the insulation cracks or the earth pin loosens, which typically takes many years of normal use.

At what point does the 65 W output limit throttle the laptop under sustained load?

When the system draws more than 65 W — for example while charging the battery and running the CPU at full turbo — the adapter will hit its current ceiling and the laptop must reduce power draw.
