Sony VGN-NS290J Power Adapter
If buying off-brand, please check on the output of amps and voltage. The Sony VGN-NS290J AC adapter provides two functions, to charge any and all batteries while simultaneously providing power for the laptop. 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 AC charger, the actual Sony brand will probably be the safest way to go. A universal AC adapter can be used but only if necessary.
Warnings the Sony power adapter needs replacing ASAP
- The unit will not work while just using AC power
- Your Sony battery refuses to charge up completely
- Most Sony AC adapters get warm when plugged in for 10 minutes or more
