Sony VGN-FW488J Power Adapter
When purchasing a replacement AC adapter, selecting the Sony OEM charger is usually going to be the safest choice. The Sony VGN-FW488J power adapter has two main uses, to charge any and all batteries and powering the laptop. If you decide to buy an non-Sony adapter, please check on both the voltage and amperage output. A universal power adapter can be used but only if necessary. Because Sony uses one power charger that is probably used on other similar units, be sure you choose the right one.
Easy warnings of a weakening Sony power adapter
- The laptop does not function without the battery installed
- Most Sony AC adapters will get warm to the touch when plugged in for 10 minutes or more
- Your Sony battery refuses to charge at all
