Sony VGN-BZ579TBB Power Adapter
If buying off-brand, please check on the output of amps and voltage. The Sony VGN-BZ579TBB power adapter is needed for two reasons, to charge up the main battery and to provide a source of power for the unit. When purchasing a replacement adapter, selecting the Sony OEM charger will probably be the safest way to go. Because Sony has been known to use a single AC adapter that is probably used on other similar units, be certain you select the correct one for the VGN-BZ579TBB model. A universal AC adapter is a possibility if you absolutely need to.
Simple indications of a deteriorating laptop charger
- The laptop does not operate while solely using the AC adapter
- Battery does not charge completely
- Most Sony AC adapters get warm when plugged in for 10 minutes or more
