Sony VGN-FW390 Power Adapter
The Sony VGN-FW390 power adapter is responsible for two things, charging the battery and to provide a source of power for the unit. If you decide to buy an non-Sony adapter, make note of the output of amps and voltage. A universal power adapter is a possibility but only if necessary. When purchasing a replacement charger, choosing the Sony brand one 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.
Subtle hints the power charger is going out
- Your Sony battery refuses to charge every time
- Most Sony AC adapters will get warm to the touch when plugged in for any length of time
- The laptop does not operate without the battery installed

A Sony VGN-FW390 power adapter should be purchased in brand new condition because of wear and tear on an old used power adapter. The Sony laptop will be happier for buying smart. Please be sure to check and double-check the manufacturers part number so you order the correct power adapter replacement. Be sure to always buy replacement parts from a site you know when buying via the internet.
