Sony VGN-CR131E Power Adapter
If buying off-brand, please check on both the voltage and amperage output. Because Sony uses one power charger that is most likely used on other laptop models, double-check the part number or model number of the adapter. When choosing a new AC adapter, selecting the Sony OEM charger will probably be the safest way to go. A universal AC adapter can be used if you absolutely need to. The Sony VGN-CR131E AC adapter provides two functions, to charge the onboard battery and to provide a source of power for the unit.
Signals your laptop charger will need to be replaced
- The majority of Sony power chargers can get quite warm when plugged in for any length of time
- The unit will not function without the battery installed
- Battery does not charge whatsoever
