Sony VGN-FW378J Power Adapter
When choosing a new charger, choosing the Sony brand one will probably be the safest way to go. If buying off-brand, make sure to check both the voltage and amperage output. The Sony VGN-FW378J AC adapter provides two functions, to charge up the main battery and powering the laptop. Because Sony uses one power charger that is probably used on other similar units, double-check the part number or model number of the adapter. A universal power adapter is another possibility but only if necessary.
Indications to watch for in a failing laptop charger
- Most Sony AC adapters get warm when plugged in for 10 minutes or more
- Battery does not charge up whatsoever
- The unit will not function while solely using the AC adapter

A Sony VGN-FW378J power adapter will be better for your laptop in brand new condition for a variety of reasons, including wear and tear on any old power adapter that may occur. The Sony laptop will thank you if you buy the right parts. Try to always purchase electronic parts from a reputable seller if you purchase through a website. Always make sure to make note of the OEM part number so you order the correct power adapter replacement.
