Sony VPCSA2BGX Power Adapter
When purchasing a replacement adapter, selecting the Sony OEM charger is usually going to be the safest choice. If you decide to buy an non-Sony adapter, make note of both the volts and amps outputs. The Sony VPCSA2BGX AC adapter is responsible for two things, to charge the onboard battery and to provide a source of power for the unit. A universal power adapter can be used but only if necessary. Because Sony uses one power charger that is probably used on other similar units, make sure you check the part number for the correct one.
Cues of a poorly performing AC adapter
- The laptop does not function while just using AC power
- Most Sony adapters can get quite warm when plugged in for 10 minutes or more
- Battery does not charge up every time
