Sony VGN-FZ340N Power Adapter
The Sony VGN-FZ340N power adapter is needed for two reasons, to charge any and all batteries while simultaneously providing power for the laptop. Because Sony has been known to use a single AC adapter that powers multiple other machines, be sure you choose the right one. A universal power adapter is a possibility if you absolutely need to. If buying off-brand, please check on the output of amps and voltage. When choosing a new adapter, choosing the Sony brand one is always going to be the safest and easiest way to go.
Some clues of a bad AC adapter
- Your Sony battery refuses to charge up whatsoever
- Most Sony adapters will get warm to the touch when they are plugged in for a period of time
- The laptop does not function while just using AC power
