Sony VGN-CS209J Power Adapter
Upon choosing a replacement AC adapter, choosing the Sony brand one 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. Because Sony has been known to use a single AC adapter that powers multiple other machines, double-check the part number or model number of the adapter. The Sony VGN-CS209J AC adapter is responsible for two things, to charge any and all batteries and to provide a source of power for the unit. A universal power adapter can be used but only if necessary.
Major symptoms your AC adapter has to be replaced
- The majority of Sony power chargers get warm when they are plugged in for a period of time
- The laptop does not work using just the AC power adapter
- Your Sony battery refuses to charge every time
