Sony PCG-FX140 Power Adapter
If you decide to buy an non-Sony adapter, make sure to check the output of amps and voltage. The Sony PCG-FX140 AC adapter is needed for two reasons, to charge up the main battery and powering the laptop. Upon choosing a replacement AC adapter, the actual Sony brand is always going to be the safest and easiest way to go. 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. A universal power adapter is a possibility if you are desperate.
Key clues of an ailing power adapter
- Most Sony adapters can get quite warm when plugged in for 10 minutes or more
- Your Sony battery refuses to charge whatsoever
- The unit will not run without the battery installed
