Sony PCG-F540K Power Adapter
If you decide to buy an non-Sony adapter, please check on both the voltage and amperage output. Because Sony has been known to use a single AC adapter that can be used on other units, be certain you select the correct one for the PCG-F540K model. A universal AC adapter can be used but only if necessary. The Sony PCG-F540K power adapter has two main uses, to charge the onboard battery while simultaneously providing power for the laptop. When purchasing a replacement AC charger, the actual Sony brand is usually going to be the safest choice.
Some clues your AC adapter is not going to last much longer
- Battery does not charge up whatsoever
- Most Sony AC adapters will get warm to the touch when plugged in for any length of time
- The unit will not operate without the battery installed
