Sony VGN-AR770U Power Adapter
If buying off-brand, please check on both the voltage and amperage output. Due to the fact that one Sony adapter powers multiple other machines, make sure you check the part number for the correct one. Upon choosing a replacement AC adapter, selecting the Sony OEM charger will probably be the safest way to go. A universal AC adapter is a possibility if yours is unavailable or backordered. The Sony VGN-AR770U AC adapter has two main uses, charging the battery and to provide a source of power for the unit.
What signals that my AC adapter will soon go out?
- Most Sony AC adapters will get very warm to the touch when they are plugged in for a period of time
- Battery does not charge completely
- The unit will not operate while just using AC power
