Sony VGN-SR190 Power Adapter
The Sony VGN-SR190 AC adapter provides two functions, charging the battery while simultaneously providing power for the laptop. When choosing a new adapter, selecting the Sony OEM charger is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, please check on the output of amps and voltage. A universal AC adapter is another possibility but only if necessary. Due to the fact that one Sony adapter is most likely used on other laptop models, be certain you select the correct one for the VGN-SR190 model.
Indications of a failing Sony power adapter
- The laptop does not run while just using AC power
- Most Sony adapters will get very warm to the touch when they are plugged in for a period of time
- Your Sony battery refuses to charge up all the time
