Sony VPCSA490X Power Adapter
If buying off-brand, make note of both the voltage and amperage output. Upon choosing a replacement AC adapter, choosing the Sony brand one is always going to be the safest and easiest way to go. The Sony VPCSA490X AC adapter is needed for two reasons, charging the battery and powering the laptop. A universal AC adapter can be used if you absolutely need to. Due to the fact that one Sony adapter is most likely used on other laptop models, double-check the part number or model number of the adapter.
What are the signs that the Sony power adapter is almost going bad?
- Your Sony battery refuses to charge every time
- Most Sony AC adapters will get warm to the touch when plugged in for 10 minutes or more
- The unit will not function without the battery installed

A Sony VPCSA490X power adapter is going to be better in factory new condition for obvious reasons, including possible wear on any older used one. Try to always purchase parts from a known seller when buying parts online. Your Sony laptop will love you more if you buy smart! It is always best to write down the model number so you order the correct power adapter replacement.
