Sony VGN-SR420J Power Adapter
When choosing a new adapter, the actual Sony brand is usually going to be the safest choice. The Sony VGN-SR420J power adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. If you decide to buy an non-Sony adapter, make note of the output of amps and voltage. Because Sony uses one power charger that is probably used on other similar units, be sure you choose the right one. A universal power adapter is a possibility if yours is unavailable or backordered.
Key symptoms of an ailing charger
- The laptop does not function without the battery installed
- The majority of Sony power chargers will get warm to the touch when they are plugged in for a period of time
- Your Sony battery refuses to charge up every time
