Sony VPCEA31FX 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 you decide to buy an non-Sony adapter, make sure to check the output of amps and voltage. When choosing a new charger, the actual Sony brand will probably be the safest way to go. A universal power adapter is another possibility if yours is unavailable or backordered. The Sony VPCEA31FX power adapter is responsible for two things, to charge up the main battery while simultaneously providing power for the laptop.
Signs the power charger is dead
- The unit will not function while solely using the AC adapter
- The majority of Sony power chargers will get very warm to the touch when plugged in for any length of time
- Your Sony battery refuses to charge up completely
