Sony VGN-Z799DHB Power Adapter
Because Sony has been known to use a single AC adapter that can be used on other units, be sure you choose the right one. When purchasing a replacement adapter, the actual Sony brand will probably be the safest way to go. A universal AC adapter is a possibility if you absolutely need to. If you decide to buy an non-Sony adapter, make note of the output of amps and voltage. The Sony VGN-Z799DHB AC adapter has two main uses, charging the battery and to provide a source of power for the unit.
