Sony PCG-F490K Power Adapter
The Sony PCG-F490K AC adapter is responsible for two things, charging the battery while simultaneously providing power for the laptop. Because Sony has been known to use a single AC adapter that is most likely used on other laptop models, make sure you check the part number for the correct one. When purchasing a replacement adapter, choosing the Sony brand one is always going to be the safest and easiest way to go. If you decide to buy an non-Sony adapter, please check on both the voltage and amperage output. A universal power adapter is another possibility but only if necessary.
Clues your power adapter will not live much longer
- Your Sony battery refuses to charge all the time
- Most Sony adapters can get quite warm when plugged in for any length of time
- The unit will not run while just using AC power
