Sony VPCSA3BGX Power Adapter
The Sony VPCSA3BGX power adapter is responsible for two things, to charge the onboard battery and powering the laptop. Upon choosing a replacement adapter, selecting the Sony OEM charger is usually going to be the safest choice. Because Sony has been known to use a single AC adapter that can be used on other units, double-check the part number or model number of the adapter. A universal power adapter can be used if you are desperate. If buying off-brand, make note of both the volts and amps outputs.
Signs of a poorly working charger
- The majority of Sony power chargers get warm when plugged in for 10 minutes or more
- Battery does not charge every time
- The unit will not run using just the AC power adapter
