Sony PCG-FX340 Power Adapter
When purchasing a replacement AC adapter, choosing the Sony brand one is usually going to be the safest choice. Because Sony uses one power charger that is most likely used on other laptop models, double-check the part number or model number of the adapter. If buying off-brand, it is imperative to note both the volts and amps outputs. The Sony PCG-FX340 AC adapter has two main uses, to charge the onboard battery and to provide a source of power for the unit. A universal power adapter can be used if yours is unavailable or backordered.
Signals your laptop charger should need replacing
- The majority of Sony power chargers will get very warm to the touch when plugged in for 10 minutes or more
- Your Sony battery refuses to charge all the time
- The unit will not work while just using AC power
