Sony PCG-FX390K Power Adapter
Because Sony uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. The Sony PCG-FX390K power adapter is responsible for two things, to charge the onboard battery and powering the laptop. When purchasing a replacement adapter, the actual Sony brand is always going to be the safest and easiest way to go. If you decide to buy an non-Sony adapter, please check on both the voltage and amperage output. A universal power adapter is another possibility but only if necessary.
Warnings your power adapter will not last the year
- Your Sony battery refuses to charge completely
- The laptop does not work without the battery installed
- Most Sony adapters will get warm to the touch when plugged in for 10 minutes or more

A Sony PCG-FX390K power adapter should be purchased in new condition due to the wear on an older one. The Sony laptop will thank you for thinking before buying. It is in your best interest to note the model number so that you correctly order the right power adapter. Make sure to try and buy computer products from a reputable seller if you purchase through a website.
