Sony VPCEF37FX Power Adapter
Due to the fact that one Sony adapter can be used on other units, be certain to thoroughly note the part number that is needed for this model. When purchasing a replacement charger, selecting the Sony OEM charger is always going to be the safest and easiest way to go. A universal power adapter is a possibility if you absolutely need to. The Sony VPCEF37FX AC adapter is needed for two reasons, to charge up the main battery and to provide a source of power for the unit. If you decide to buy an non-Sony adapter, it is imperative to note both the voltage and amperage output.
What are the signs that the AC adapter is in need of replacing?
- Most Sony AC adapters can get quite warm when they are plugged in for a period of time
- The laptop does not run using just the AC power adapter
- Your Sony battery refuses to charge whatsoever
