Sony VGN-SR490D Power Adapter
The Sony VGN-SR490D AC adapter is needed for two reasons, to charge the onboard battery and powering the laptop. When choosing a new charger, choosing the Sony brand one is usually going to be the safest choice. Because Sony uses one power charger that can be used on other units, be certain you select the correct one for the VGN-SR490D model. A universal AC adapter is another possibility if yours is unavailable or backordered. If buying off-brand, make note of both the volts and amps outputs.
What red flags are there that my power adapter is not working properly?
- The unit will not run while just using AC power
- Your Sony battery refuses to charge all the time
- Most Sony AC adapters can get quite warm when they are plugged in for a period of time

Always buy parts from a reputable seller if you buy anything online. Please be sure to note the OEM part number so that you correctly order the right power adapter. The Sony VGN-SR490D laptop will be better off for buying the right way! Sony VGN-SR490D power adapter will be better for your laptop brand new due to possible wear on any old power adapter that may occur.
