Sony VPCSB4AFX Power Adapter
Because Sony has been known to use a single AC adapter that is probably used on other similar units, be certain to thoroughly note the part number that is needed for this model. The Sony VPCSB4AFX AC adapter is needed for two reasons, charging the battery while simultaneously providing power for the laptop. A universal power adapter is a possibility if yours is unavailable or backordered. If your decision is to purchase a different brand charger, make sure to check both the voltage and amperage output. When purchasing a replacement adapter, the actual Sony brand is the best one to choose.
Easy warnings of a poorly working laptop charger
- Most Sony adapters will get very warm to the touch when plugged in for any length of time
- Battery does not charge up completely
- The laptop does not run while solely using the AC adapter
