Sony VGN-UX390N Power Adapter
Upon choosing a replacement AC adapter, the actual Sony brand is usually going to be the safest choice. If your decision is to purchase a different brand charger, make note of the output of amps and voltage. Because Sony has been known to use a single AC adapter that powers multiple other machines, be sure you choose the right one. A universal AC adapter can be used if you absolutely need to. The Sony VGN-UX390N power adapter provides two functions, to charge any and all batteries and powering the laptop.
Major clues of a declining charger
- Battery does not charge up every time
- The laptop does not function while solely using the AC adapter
- The majority of Sony power chargers get warm when they are plugged in for a period of time
