Sony VGN-A290 Power Adapter
The Sony VGN-A290 AC adapter is responsible for two things, to charge up the main battery while simultaneously providing power for the laptop. Because Sony has been known to use a single AC adapter that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. If buying off-brand, it is imperative to note the output of amps and voltage. A universal power adapter is another possibility but only if necessary. Upon choosing a replacement AC charger, choosing the Sony brand one is the best one to choose.
Simple signals your power adapter is dead
- Battery does not charge up every time
- Most Sony adapters will get very warm to the touch when plugged in for any length of time
- The laptop does not operate without the battery installed

A Sony VGN-A290 power adapter should be purchased brand new due to possible wear on any old one. Be sure to always order replacement parts from a known seller if you purchase through a website. Please be sure to check and double-check the manufacturers part number before buying a power adapter replacement. The Sony laptop will love you more if you buy smart!
