Sony VPCSB190X Power Adapter
When purchasing a replacement AC charger, choosing the Sony brand one will probably be the safest way to go. If buying off-brand, please check on both the voltage and amperage output. A universal AC adapter can be used if you absolutely need to. The Sony VPCSB190X power adapter has two main uses, to charge the onboard battery while simultaneously providing power for the laptop. Because Sony has been known to use a single AC adapter that powers multiple other machines, be certain you select the correct one for the VPCSB190X model.
How can I tell if my power adapter needs to be replaced?
- Most Sony adapters get warm when plugged in for any length of time
- The unit will not run while just using AC power
- Your Sony battery refuses to charge up at all
