Sony VGN-CR309E Power Adapter
The Sony VGN-CR309E power adapter is responsible for two things, to charge the onboard battery while simultaneously providing power for the laptop. When choosing a new AC adapter, the actual Sony brand will probably be the safest way to go. Due to the fact that one Sony adapter is most likely used on other laptop models, double-check the part number or model number of the adapter. A universal AC adapter can be used if you are desperate. If you decide to buy an non-Sony adapter, please check on both the voltage and amperage output.
Major warnings poorly running charger
- Most Sony AC adapters can get quite warm when plugged in for 10 minutes or more
- The laptop does not operate while just using AC power
- Your Sony battery refuses to charge up at all
