Replacement AC adapter for Sony VGN-S series

This 19.5V 3.96A 75W AC adapter replaces the original charger for Sony VGN-S550 VGN-S550P/B VGN-S55SP/S VGN-S560 VGN-S560P/B laptops. It accepts 100 to 240V AC input at 50 to 60Hz and delivers a regulated 19.5V DC output at 3.96A. The unit ships with a region-specific power cord so it works straight from the wall.

Thermals noise and power draw in normal use

The adapter runs on standard mains frequencies of 50 to 60Hz and draws up to 75W from the outlet. No fan is fitted, so operation is silent. Heat is dissipated passively through the enclosure during typical charging sessions. The 24-month warranty period reflects the supplier's confidence in sustained reliability.

Build fit connector and cable requirements

A 6.5mm by 4.4mm barrel connector mates with the laptop's DC-in jack. The package includes one AC adapter and one power cord with a US UK EU or AU plug that matches your mains socket. No additional cables or tools are required for installation. Buyers whose laptops use a different barrel size or voltage cannot use this unit.

Questions about this item

How do I connect the 6.5mm by 4.4mm barrel connector to my Sony VGN-S550 and what mistake should I avoid?

Align the centre pin and outer sleeve, then push straight in until it seats firmly; forcing it at an angle bends the pin and breaks the DC jack.

Which part of this 75W adapter will wear out first and need replacing?

The detachable mains cord and the DC cable near the barrel plug flex repeatedly; replace either when insulation cracks or the connector becomes intermittent.

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

The internal components hit their maximum safe temperature and the protection circuit shuts the output down until the adapter cools.
