Sony VPCEA3JGX Power Adapter
Because Sony uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one. When choosing a new charger, choosing the Sony brand one is always going to be the safest and easiest way to go. The Sony VPCEA3JGX power adapter provides two functions, to charge up the main battery while simultaneously providing power for the laptop. A universal AC adapter can be used but only if necessary. If your decision is to purchase a different brand charger, make note of both the voltage and amperage output.
Indications your AC adapter is failing
- Most Sony adapters get warm when plugged in for any length of time
- The laptop does not run while solely using the AC adapter
- Your Sony battery refuses to charge at all
