Sony VGN-AW290J-AH Power Adapter
Because Sony has been known to use a single AC adapter that is probably used on other similar units, be sure you choose the right one. The Sony VGN-AW290J-AH power adapter is responsible for two things, to charge any and all batteries and to provide a source of power for the unit. If your decision is to purchase a different brand charger, it is imperative to note both the volts and amps outputs. When choosing a new charger, the actual Sony brand is usually going to be the safest choice. A universal power adapter is a possibility if you are desperate.
Indications your AC adapter is failing
- Your Sony battery refuses to charge every time
- The majority of Sony power chargers will get warm to the touch when plugged in for any length of time
- The laptop does not function using just the AC power adapter
