Sony VGN-FW550F Power Adapter
The Sony VGN-FW550F AC adapter provides two functions, charging the battery and to provide a source of power for the unit. Due to the fact that one Sony adapter is most likely used on other laptop models, be certain to thoroughly note the part number that is needed for this model. If you decide to buy an non-Sony adapter, make sure to check both the volts and amps outputs. When choosing a new AC charger, selecting the Sony OEM charger will probably be the safest way to go. A universal AC adapter can be used but only if necessary.
Key indicators that my AC adapter will soon go out?
- The laptop does not run using just the AC power adapter
- Your Sony battery refuses to charge whatsoever
- Most Sony adapters will get warm to the touch when they are plugged in for a period of time
