Sony VGN-FW490J Power Adapter
Because Sony has been known to use a single AC adapter that can be used on other units, make sure you check the part number for the correct one. Upon choosing a replacement adapter, selecting the Sony OEM charger is usually going to be the safest choice. A universal power adapter can be used if you are desperate. The Sony VGN-FW490J AC adapter is needed for two reasons, to charge up the main battery while simultaneously providing power for the laptop. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs.
Simple signals your power adapter will eventually need to be replaced
- Most Sony AC adapters can get quite warm when they are plugged in for a period of time
- The laptop does not function without the battery installed
- Battery does not charge every time
