Sony VGN-UX490N Power Adapter
The Sony VGN-UX490N AC adapter has two main uses, to charge the onboard battery while simultaneously providing power for the laptop. If buying off-brand, it is imperative to note both the voltage and amperage output. A universal power adapter is a possibility if you are desperate. Because Sony has been known to use a single AC adapter that is probably used on other similar units, be certain you select the correct one for the VGN-UX490N model. Upon choosing a replacement AC charger, the actual Sony brand is the best one to choose.
Simple signals the Sony power adapter has little time left
- The unit will not function without the battery installed
- The majority of Sony power chargers will get very warm to the touch when they are plugged in for a period of time
- Battery does not charge at all
