Sony VPCCB290X Power Adapter
Because Sony has been known to use a single AC adapter that is most likely used on other laptop models, be certain to thoroughly note the part number that is needed for this model. When choosing a new adapter, the actual Sony brand is the best one to choose. The Sony VPCCB290X power adapter provides two functions, to charge the onboard battery while simultaneously providing power for the laptop. A universal power adapter is a possibility if you absolutely need to. If you decide to buy an non-Sony adapter, make note of both the volts and amps outputs.
Cues of an ailing AC adapter
- The unit will not run using just the AC power adapter
- Battery does not charge up completely
- Most Sony AC adapters will get warm to the touch when they are plugged in for a period of time
