75 W 19.5 V AC adapter for Sony and HP laptops

This 75-watt power supply delivers 19.5 volts at 3.96 amps to compatible Sony VPCEB29GX and HP laptops. It accepts worldwide mains input from 100 to 240 volts at 50 to 60 hertz. A country-specific power cord with US, UK, EU or AU plug is included in the package.

Silent convection cooling with universal mains input

The brick uses passive convection cooling so it runs without fan noise in normal use. Efficiency meets typical adapter standards for a 75 W unit drawing from 100 to 240 V AC. No moving parts mean there is no audible whine or vibration during charging.

6.5 mm by 4.4 mm barrel connector

The DC plug measures 6.5 millimetres outer diameter by 4.4 millimetres inner diameter for a secure fit on supported models. A removable AC cord lets you swap the mains lead for travel without replacing the whole adapter. The unit ships new with a 24-month manufacturer warranty.

Questions about this item

How do I connect the 6.5mm by 4.4mm barrel tip to my laptop and which step causes charging to fail?

Plug the barrel tip fully into the laptop DC jack until it seats firmly; a loose or angled insertion is the common mistake that prevents the 19.5V 3.96A output from engaging.

Which part of this 75W adapter will need replacement first and after roughly how long?

The detachable power cord and the barrel connector see the most wear; with daily plugging they typically last several years before the cord frays or the tip loosens.

What thermal limit appears first when this 19.5V 3.96A charger runs at full load for hours?

The internal protection triggers at the 75W continuous rating, reducing output or shutting down if the case temperature exceeds the design threshold.
