Sony VGN-NR330E Power Adapter
If you decide to buy an non-Sony adapter, please check on both the volts and amps outputs. Because Sony has been known to use a single AC adapter that is most likely used on other laptop models, double-check the part number or model number of the adapter. The Sony VGN-NR330E power adapter is needed for two reasons, charging the battery and to provide a source of power for the unit. When choosing a new adapter, the actual Sony brand is usually going to be the safest choice. A universal AC adapter is another possibility but only if necessary.
Easy warnings the power charger should be replaced
- The unit will not work without the battery installed
- Most Sony AC adapters get warm when plugged in for 10 minutes or more
- Your Sony battery refuses to charge completely
