75W 19.5V AC adapter for Sony VGN-BX series

This 75W AC adapter supplies 19.5V at 3.96A for Sony VGN-BX740NW, VGN-BX740P, VGN-BX740PS and VGN-BX740PW laptops. It accepts 100 to 240V AC input at 50 to 60Hz for worldwide use. The barrel connector measures 6.5mm by 4.4mm. A matching power cord for your region is included.

Steady 75W delivery through the 6.5mm barrel

The unit maintains a continuous 75W DC output at 19.5V and 3.96A during extended charging or heavy workloads. Wide-range AC input handles voltage fluctuations without tripping. No active cooling is present, so the enclosure relies on passive dissipation. The 24-month warranty period reflects the expected service life under normal conditions.

Plug-in replacement with 6.5mm*4.4mm tip

Installation requires only connecting the supplied mains cord and inserting the barrel tip into the laptop power jack. The fixed 6.5mm by 4.4mm connector cannot be swapped for other tip sizes. Buyers whose laptops use a different barrel diameter or a USB-C power port cannot use this adapter. Polarity matches the listed Sony models; verify the centre-positive symbol on your original charger before connecting.

Does the 75W adapter run hot or make noise when used continuously?

The unit delivers 19.5V at 3.96A with a wide 100–240V 50–60Hz input and has no fan, so it stays quiet and only warm under normal all-day loads.

My laptop only has a 6.5mm x 4.4mm barrel port — is that the only cable I need?

Yes, the connector matches 6.5mm*4.4mm and the package includes a region-specific power cord, so no extra cable is required.

Will this 19.5V 3.96A charger work with my older Sony VGN-BX740 series laptop?

The adapter is listed for VGN-BX740NW, VGN-BX740P, VGN-BX740PS and VGN-BX740PW models, matching their 19.5V 3.96A 75W requirement.
