Replacement 75W adapter for Sony VGN-S series

This 19.5V 3.96A AC adapter supplies 75W to compatible Sony VGN-S470P/S, VGN-S4HP/B, VGN-S4HRP/B, VGN-S4M/S and VGN-S4VP/B laptops. It accepts 100 to 240V AC input at 50 or 60Hz and delivers 19.5V DC at 3.96A through a 6.5mm by 4.4mm barrel connector. A country-specific power cord is included in the box.

Cooling and power behaviour

The unit runs passively without a fan, so it produces no audible noise during normal operation. Heat is dissipated through the external casing, which becomes warm but not hot when delivering the rated 75W load. Power draw from the wall matches the 100 to 240V input range, automatically adjusting to local mains voltage.

Upgrade context and fit

This adapter replaces a lost or failed original charger for the listed Sony models; it is not suitable for laptops that require a different voltage, current or connector size. Buyers who need a higher wattage unit or a USB-C power delivery solution should look elsewhere. The 24-month warranty covers defects in materials and workmanship.

Questions about this item

How do I connect the 6.5mm by 4.4mm barrel plug to my Sony VGN-S series laptop?

Align the 6.5mm outer and 4.4mm inner diameter connector with the laptop's DC-in jack and push straight in until seated; the step often missed is verifying the tip polarity matches the 19.5V 3.96A rating before powering on.

When should I replace the detachable AC power cord that ships with the adapter?

Replace the cord if the insulation cracks, the plug pins bend, or the connector becomes loose; the cord handles 100 to 240V at 50 to 60Hz so any damage compromises safety and charging reliability.

What thermal limit appears first when the 75W adapter runs continuously at full 19.5V 3.96A load?

The internal over-temperature protection triggers first, shutting down output until the unit cools; sustained maximum 75W draw in a confined space accelerates this cycle and shortens component life.
