Sony VGN-FJ290 Power Adapter
When choosing a new AC charger, selecting the Sony OEM charger will probably be the safest way to go. If you decide to buy an non-Sony adapter, it is imperative to note the output of amps and voltage. 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 is a possibility but only if necessary. The Sony VGN-FJ290 AC adapter has two main uses, charging the battery while simultaneously providing power for the laptop.
What symptoms are present when the power adapter is about to go out?
- Battery does not charge up at all
- Most Sony adapters will get warm to the touch when they are plugged in for a period of time
- The laptop does not function while just using AC power
