Sony PCG-FX140K Power Adapter
The Sony PCG-FX140K power adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. Because Sony has been known to use a single AC adapter that can be used on other units, double-check the part number or model number of the adapter. When choosing a new charger, choosing the Sony brand one is always going to be the safest and easiest way to go. If you decide to buy an non-Sony adapter, make note of both the volts and amps outputs. A universal AC adapter can be used if you absolutely need to.
What are some indications that my power adapter is dying?
- Battery does not charge up every time
- The unit will not operate without the battery installed
- Most Sony AC adapters will get very warm to the touch when they are plugged in for a period of time
