Replacement power supply for Sony VGN-SR series

This 75 W AC adapter delivers 19.5 V at 3.96 A for Sony VGN-SR29VN/S VGN-SR29XN/S VGN-SR31M/S VGN-SR39VN/S notebooks. It accepts 100-240 V input at 50-60 Hz for worldwide use. A 6.5 mm by 4.4 mm barrel connector fits the DC jack on these models. The package includes the adapter and a country-specific power cord.

Suitable for owners of the listed Sony models

Users with laptops that require a different voltage, current or connector size should look elsewhere. Buyers who need a USB-C power delivery solution cannot use this barrel-type adapter. Anyone missing the exact model number on their device should verify compatibility before ordering.

6.5 mm by 4.4 mm barrel connector

The centre-positive tip measures 6.5 mm outer diameter and 4.4 mm inner diameter. This physical interface determines whether the adapter plugs into the laptop. Confirm the socket on your Sony VGN-SR machine matches these dimensions before purchase.

Questions about this item

How often will the 6.5mm x 4.4mm DC connector need replacing under daily use?

The connector is a standard barrel type rated for thousands of insertion cycles; it typically lasts the adapter's lifetime unless physically damaged.

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

The internal components are designed to operate within safe temperature limits at the rated 19.5V 3.96A output; the enclosure dissipates heat passively.

How much heat and noise does the 19.5V 75W unit produce when powering a laptop all day?

It runs silently with no fan; the case warms to a moderate temperature during continuous 75W operation but stays within normal limits for a sealed adapter.
