Sony VGN-NR310E Power Adapter
If buying off-brand, please check on the output of amps and voltage. The Sony VGN-NR310E power adapter has two main uses, charging the battery while simultaneously providing power for the laptop. A universal power adapter can be used if you absolutely need to. Because Sony has been known to use a single AC adapter that is probably used on other similar units, make sure you check the part number for the correct one. Upon choosing a replacement adapter, selecting the Sony OEM charger is always going to be the safest and easiest way to go.
What symptoms are present when the laptop charger will soon go out?
- Battery does not charge up all the time
- The unit will not work without the battery installed
- Most Sony AC adapters will get very warm to the touch when they are plugged in for a period of time
