Sony VGN-FW400 Power Adapter
When purchasing a replacement AC adapter, selecting the Sony OEM charger is the best one to choose. If buying off-brand, it is imperative to note both the voltage and amperage output. The Sony VGN-FW400 power adapter has two main uses, to charge up the main battery and powering the laptop. A universal power adapter is another possibility but only if necessary. Because Sony has been known to use a single AC adapter that is probably used on other similar units, make sure you check the part number for the correct one.
General indicators that your AC adapter is in dire straights
- Battery does not charge up every time
- The laptop does not operate without the battery installed
- The majority of Sony power chargers can get quite warm when plugged in for 10 minutes or more
