Sony VGN-BX740N Power Adapter
The Sony VGN-BX740N power adapter provides two functions, charging the battery and to provide a source of power for the unit. Because Sony has been known to use a single AC adapter that powers multiple other machines, double-check the part number or model number of the adapter. If buying off-brand, please check on both the voltage and amperage output. When choosing a new AC charger, the actual Sony brand is always going to be the safest and easiest way to go. A universal AC adapter is a possibility if yours is unavailable or backordered.
Signs the Sony power adapter will need replacing
- Most Sony adapters get warm when they are plugged in for a period of time
- Battery does not charge up whatsoever
- The laptop does not run without the battery installed
