Sony VGN-CS290N Power Adapter
Due to the fact that one Sony adapter powers multiple other machines, be certain you select the correct one for the VGN-CS290N model. Upon choosing a replacement AC adapter, the actual Sony brand is the best one to choose. The Sony VGN-CS290N power adapter provides two functions, to charge the onboard battery while simultaneously providing power for the laptop. If you decide to buy an non-Sony adapter, it is imperative to note the output of amps and voltage. A universal power adapter is another possibility if yours is unavailable or backordered.
What to see if the AC adapter really needs to be replaced?
- Most Sony adapters will get very warm to the touch when plugged in for 10 minutes or more
- Your Sony battery refuses to charge up every time
- The laptop does not run without the battery installed
