Sony VPCSB390X Power Adapter
If you decide to buy an non-Sony adapter, please check on both the volts and amps outputs. Due to the fact that one Sony adapter can be used on other units, double-check the part number or model number of the adapter. The Sony VPCSB390X power adapter is needed for two reasons, to charge up the main battery and powering the laptop. When choosing a new adapter, the actual Sony brand is always going to be the safest and easiest way to go. A universal AC adapter is a possibility but only if necessary.
Easy warnings of a faulty charger
- Most Sony adapters will get very warm to the touch when plugged in for any length of time
- Battery does not charge completely
- The unit will not run while solely using the AC adapter
