Sony PCG-K23 Power Adapter
If buying off-brand, make sure to check both the voltage and amperage output. The Sony PCG-K23 power adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. Upon choosing a replacement AC charger, selecting the Sony OEM charger is the best one to choose. Because Sony uses one power charger that can be used on other units, double-check the part number or model number of the adapter. A universal power adapter is another possibility if yours is unavailable or backordered.
Symptoms your laptop charger will soon need to be replaced
- Your Sony battery refuses to charge up every time
- The unit will not function while just using AC power
- The majority of Sony power chargers will get warm to the touch when they are plugged in for a period of time
