Sony VGN-B55S Power Adapter
If you decide to buy an non-Sony adapter, please check on the output of amps and voltage. Upon choosing a replacement AC adapter, the actual Sony brand will probably be the safest way to go. Because Sony uses one power charger that is most likely used on other laptop models, make sure you check the part number for the correct one. A universal power adapter can be used if you are desperate. The Sony VGN-B55S AC adapter has two main uses, charging the battery while simultaneously providing power for the laptop.
Major indications to watch for in a failing power adapter
- The laptop does not run using just the AC power adapter
- Your Sony battery refuses to charge up all the time
- The majority of Sony power chargers will get warm to the touch when plugged in for 10 minutes or more
