Sony VGN-SR390 Power Adapter
The Sony VGN-SR390 AC adapter is responsible for two things, charging the battery and powering the laptop. If you decide to buy an non-Sony adapter, make sure to check the output of amps and voltage. Because Sony uses one power charger that can be used on other units, be certain you select the correct one for the VGN-SR390 model. When purchasing a replacement adapter, choosing the Sony brand one is always going to be the safest and easiest way to go. A universal AC adapter can be used if you absolutely need to.
What warnings should I watch out for to know if my Sony AC adapter is in need of a replacement?
- Battery does not charge at all
- Most Sony adapters will get very warm to the touch when plugged in for any length of time
- The unit will not operate while solely using the AC adapter

A Sony VGN-SR390 power adapter should be purchased new due to the wear on any older used one. It is always best to re-check the manufacturers part number before placing an order for a new power adapter. Always get electronic parts from a known seller when buying via the internet. The Sony laptop will be happier if you buy smart!
