Sony VGN-CS390 Power Adapter
Upon choosing a replacement adapter, choosing the Sony brand one is usually going to be the safest choice. Because Sony has been known to use a single AC adapter that powers multiple other machines, make sure you check the part number for the correct one. A universal power adapter is another possibility if you are desperate. The Sony VGN-CS390 AC adapter provides two functions, charging the battery and powering the laptop. If your decision is to purchase a different brand charger, please check on both the volts and amps outputs.
Major clues the power charger is in dire need of a replacement
- The unit will not function using just the AC power adapter
- Your Sony battery refuses to charge up completely
- Most Sony adapters will get warm to the touch when they are plugged in for a period of time
