Sony VGN-CR220E Power Adapter
The Sony VGN-CR220E AC adapter is needed for two reasons, charging the battery and powering the laptop. Due to the fact that one Sony adapter is most likely used on other laptop models, make sure you check the part number for the correct one. A universal power adapter can be used but only if necessary. When purchasing a replacement AC charger, choosing the Sony brand one is usually going to be the safest choice. If you decide to buy an non-Sony adapter, make note of both the volts and amps outputs.
What to see if the Sony AC adapter is about to fail?
- Your Sony battery refuses to charge up every time
- Most Sony adapters can get quite warm when plugged in for 10 minutes or more
- The laptop does not operate using just the AC power adapter
