Sony VGN-AW190N Power Adapter
Upon choosing a replacement adapter, choosing the Sony brand one is the best one to choose. The Sony VGN-AW190N AC adapter is needed for two reasons, to charge any and all batteries while simultaneously providing power for the laptop. Because Sony has been known to use a single AC adapter that is most likely used on other laptop models, be sure you choose the right one. A universal AC adapter can be used if you are desperate. If buying off-brand, please check on both the voltage and amperage output.
Signals of an inadequate power adapter
- The majority of Sony power chargers get warm when plugged in for any length of time
- The unit will not work while just using AC power
- Battery does not charge every time
