Sony VGN-AR390E Power Adapter
Because Sony uses one power charger that powers multiple other machines, be certain to thoroughly note the part number that is needed for this model. If buying off-brand, make sure to check both the voltage and amperage output. The Sony VGN-AR390E AC adapter is responsible for two things, to charge any and all batteries while simultaneously providing power for the laptop. When choosing a new adapter, choosing the Sony brand one is always going to be the safest and easiest way to go. A universal power adapter can be used if yours is unavailable or backordered.
Main clues your laptop charger is going out
- Your Sony battery refuses to charge at all
- The laptop does not function using just the AC power adapter
- Most Sony adapters will get very warm to the touch when plugged in for 10 minutes or more
