  • Powers Sony Vaio R505 series laptops reliably

Compatible Sony Vaio & Bravia Power Adapter

This 90-watt AC adapter replaces the Sony ZM-90W unit and supplies 19.5 volts at up to 4.7 amps. It fits the Vaio PCG-R505 series and numerous Bravia KDL television models ranging from 24 to 55 inches. The unit accepts a universal 100 to 240 volt input for worldwide use. It is a non-OEM replacement built to match the original specifications.

Protection Features and Thermal Behaviour

Over-voltage and over-heat protection circuits guard both the adapter and the connected device during normal operation. The supply also supports lower-current 85-watt, 3.9-amp and 3.3-amp loads without adjustment. No fan is fitted, so the adapter runs silently while delivering its rated output. The compact enclosure dissipates heat through its outer surface.

Included Mains Cord and Ready-to-Use Operation

A standard mains cord is bundled so the adapter can be plugged in immediately without sourcing a separate cable. No driver installation or software configuration is required for either the laptops or the televisions. The package contains only the power supply and the cord, keeping setup straightforward. Buyers needing a higher wattage unit or a different connector type will not be served by this model.

Questions about this item

How do I connect the adapter to my Sony Vaio PCG-R505 series laptop, and which step is commonly missed?

Plug the barrel connector firmly into the laptop's DC-in jack until it clicks, then attach the IEC C7 mains cord to the adapter before connecting to a 100-240V outlet; users often skip fully seating the barrel plug.

What part will need replacement first on this 90W 19.5V 4.7A adapter under normal use?

The IEC C7 figure-8 mains cord and the DC barrel cable are the wear items; the adapter body has over-voltage and over-heat protection but no user-serviceable parts.

At what sustained load does the 19.5V 4.7A 90W output hit its thermal limit first?

Continuous operation at the full 90W (19.5V 4.7A) will trigger the built-in over-heat protection before the lower 85W (19.5V 4.35A) compatibility rating is reached.
