Sony VGN-CR407E Power Adapter
If you decide to buy an non-Sony adapter, please check on both the volts and amps outputs. Upon choosing a replacement adapter, selecting the Sony OEM charger will probably be the safest way to go. The Sony VGN-CR407E AC adapter is needed for two reasons, charging the battery while simultaneously providing power for the laptop. A universal power adapter is another possibility if you are desperate. Because Sony uses one power charger that is most likely used on other laptop models, be sure you choose the right one.
Some warnings the Sony power adapter will eventually need to be replaced
- The laptop does not operate while just using AC power
- Most Sony adapters get warm when they are plugged in for a period of time
- Battery does not charge up completely
