Sony VGN-FW390J Power Adapter
If buying off-brand, make sure to check the output of amps and voltage. Because Sony uses one power charger that powers multiple other machines, make sure you check the part number for the correct one. When purchasing a replacement AC adapter, the actual Sony brand is the best one to choose. The Sony VGN-FW390J power adapter has two main uses, charging the battery and to provide a source of power for the unit. A universal power adapter is a possibility but only if necessary.
Major clues the power charger is in dire straights
- Battery does not charge up all the time
- The majority of Sony power chargers will get very warm to the touch when plugged in for 10 minutes or more
- The unit will not run using just the AC power adapter
