Sony VGN-SR190E Power Adapter
When purchasing a replacement adapter, choosing the Sony brand one is usually going to be the safest choice. The Sony VGN-SR190E power adapter is responsible for two things, to charge the onboard battery while simultaneously providing power for the laptop. If you decide to buy an non-Sony adapter, it is imperative to note both the voltage and amperage output. A universal AC adapter is a possibility if you absolutely need to. Because Sony uses one power charger that is most likely used on other laptop models, be certain you select the correct one for the VGN-SR190E model.
Clues to watch for to know the power charger will not live much longer
- The majority of Sony power chargers get warm when plugged in for 10 minutes or more
- The unit will not run using just the AC power adapter
- Your Sony battery refuses to charge all the time
