Sony VGN-SR Power Adapter
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-SR model. The Sony VGN-SR AC adapter has two main uses, to charge any and all batteries and powering the laptop. If you decide to buy an non-Sony adapter, it is imperative to note both the voltage and amperage output. When purchasing a replacement adapter, the actual Sony brand is always going to be the safest and easiest way to go. A universal power adapter can be used but only if necessary.
Red flags your AC adapter is going out
- The laptop does not work without the battery installed
- Most Sony AC adapters will get very warm to the touch when plugged in for 10 minutes or more
- Battery does not charge at all
