Sony PCG-F420 Power Adapter
Due to the fact that one Sony adapter is most likely used on other laptop models, be sure you choose the right one. When choosing a new adapter, selecting the Sony OEM charger is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, it is imperative to note the output of amps and voltage. The Sony PCG-F420 AC adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. A universal power adapter can be used if yours is unavailable or backordered.
Main clues the Sony power adapter needs a replacement ASAP
- Most Sony adapters get warm when plugged in for any length of time
- The laptop does not run while solely using the AC adapter
- Your Sony battery refuses to charge whatsoever
