Sony VGN-FW490 Power Adapter
If you decide to buy an non-Sony adapter, make sure to check the output of amps and voltage. The Sony VGN-FW490 power adapter has two main uses, to charge any and all batteries while simultaneously providing power for the laptop. Because Sony uses one power charger that powers multiple other machines, make sure you check the part number for the correct one. Upon choosing a replacement AC adapter, the actual Sony brand will probably be the safest way to go. A universal AC adapter is a possibility but only if necessary.
Major signs of an unhealthy Sony power adapter
- The laptop does not function without the battery installed
- Your Sony battery refuses to charge all the time
