Sony VGN-AR730E Power Adapter
If you decide to buy an non-Sony adapter, please check on the output of amps and voltage. Due to the fact that one Sony adapter is probably used on other similar units, double-check the part number or model number of the adapter. The Sony VGN-AR730E power adapter is needed for two reasons, to charge the onboard battery and to provide a source of power for the unit. When purchasing a replacement adapter, the actual Sony brand is the best one to choose. A universal power adapter can be used if you are desperate.
Easy warnings of a poorly working AC adapter
- Battery does not charge whatsoever
- Most Sony adapters get warm when plugged in for any length of time
- The laptop does not function using just the AC power adapter
