Sony VPCSB490X Power Adapter
If you decide to buy an non-Sony adapter, it is imperative to note both the voltage and amperage output. The Sony VPCSB490X AC adapter has two main uses, to charge the onboard battery and to provide a source of power for the unit. Due to the fact that one Sony adapter can be used on other units, be sure you choose the right one. Upon choosing a replacement AC adapter, selecting the Sony OEM charger is usually going to be the safest choice. A universal power adapter is another possibility if you absolutely need to.
What symptoms are present when the Sony power adapter has to be replaced?
- Most Sony adapters will get very warm to the touch when they are plugged in for a period of time
- Your Sony battery refuses to charge up whatsoever
- The unit will not work without the battery installed
