Sony VGN-AR790U Power Adapter
Upon choosing a replacement charger, the actual Sony brand is always going to be the safest and easiest way to go. The Sony VGN-AR790U power adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. Due to the fact that one Sony adapter powers multiple other machines, double-check the part number or model number of the adapter. If you decide to buy an non-Sony adapter, make sure to check both the voltage and amperage output. A universal power adapter is a possibility if yours is unavailable or backordered.
General indicators that your the power charger is on its last leg
- The unit will not work while solely using the AC adapter
- Battery does not charge whatsoever
- Most Sony adapters will get very warm to the touch when they are plugged in for a period of time
