65 W AC adapter for HP Dv5128tx and Dv5129 models

This 65 W power supply delivers 18.5 V at 3.5 A for compatible HP laptops including the Dv5128tx, Dv5129eu and Dv5129tx. It accepts a universal AC input range of 100 to 240 V at 50 to 60 Hz. The connector features a 1.7 mm internal diameter and 4.8 mm external diameter. An AC power cord is included in the package.

Thermals, noise and power draw in normal use

The adapter draws up to 65 W from the mains and converts it to a regulated 18.5 V DC output for the laptop. As an external brick, it operates silently with no moving parts. Heat is dissipated passively through the enclosure during normal charging and operation. The unit is supplied new with a two-year warranty.

Questions about this item

How do I connect the 1.7 mm internal-diameter plug to the Dv5128tx?

Align the centre pin with the laptop socket and push straight in until it seats firmly; forcing it at an angle bends the pin and breaks the connection.

When will the included AC power cord need replacing?

Replace the cord if the insulation cracks, the plug pins bend, or the connector becomes loose after repeated 100–240 V 50–60 Hz mains cycles.
