Sony PCG-631M Power Adapter
The Sony PCG-631M AC adapter is needed for two reasons, charging the battery and to provide a source of power for the unit. 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 is probably used on other similar units, be certain you select the correct one for the PCG-631M model. If you decide to buy an non-Sony adapter, make sure to check both the volts and amps outputs. A universal power adapter can be used if you absolutely need to.
Simple warnings that your charger will soon go out?
- Your Sony battery refuses to charge at all
- Most Sony AC adapters will get very warm to the touch when plugged in for 10 minutes or more
- The laptop does not function while solely using the AC adapter
