Sony VGN-CR390 Power Adapter
When choosing a new AC charger, choosing the Sony brand one is always going to be the safest and easiest way to go. If your decision is to purchase a different brand charger, make sure to check the output of amps and voltage. A universal power adapter is a possibility but only if necessary. Because Sony uses one power charger that powers multiple other machines, be sure you choose the right one. The Sony VGN-CR390 power adapter is needed for two reasons, to charge the onboard battery and to provide a source of power for the unit.
Indications your laptop charger needs a replacement ASAP
- The majority of Sony power chargers will get warm to the touch when plugged in for 10 minutes or more
- The laptop does not operate while just using AC power
- Your Sony battery refuses to charge completely
