Sony VGN-SR140N Power Adapter
Because Sony has been known to use a single AC adapter that is probably used on other similar units, be sure you choose the right one. If you decide to buy an non-Sony adapter, make note of both the voltage and amperage output. The Sony VGN-SR140N power adapter is responsible for two things, charging the battery and to provide a source of power for the unit. When choosing a new AC adapter, choosing the Sony brand one is usually going to be the safest choice. A universal power adapter can be used if yours is unavailable or backordered.
Some clues your AC adapter will have to be replaced
- Most Sony adapters get warm when plugged in for any length of time
- The laptop does not run using just the AC power adapter
- Battery does not charge up every time

A Sony VGN-SR140N power adapter should really be bought in brand new condition for obvious reasons, including possible wear on any older used one. It is in your best interest to note the OEM part number before placing an order for a new power adapter. The Sony laptop will thank you for buying the right way! Always buy parts from a site you know when you buy your parts online.
