Sony VGN-NR370N Power Adapter
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. If your decision is to purchase a different brand charger, please check on the output of amps and voltage. A universal power adapter is another possibility if yours is unavailable or backordered. The Sony VGN-NR370N AC adapter has two main uses, to charge any and all batteries and powering the laptop. When purchasing a replacement AC charger, the actual Sony brand will probably be the safest way to go.
Signals of a poorly performing AC adapter
- Battery does not charge up every time
- The majority of Sony power chargers get warm when plugged in for 10 minutes or more
- The laptop does not operate while just using AC power
