Sony VGN-CS290J Power Adapter
If you decide to buy an non-Sony adapter, make sure to check the output of amps and voltage. The Sony VGN-CS290J power adapter is responsible for two things, to charge any and all batteries and to provide a source of power for the unit. Upon choosing a replacement AC charger, selecting the Sony OEM charger is the best one to choose. A universal AC adapter is another possibility if yours is unavailable or backordered. Because Sony uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one.
Key indicators that my Sony power adapter needs replacing?
- Battery does not charge every time
- The laptop does not work using just the AC power adapter
- Most Sony AC adapters will get warm to the touch when they are plugged in for a period of time
