Sony VPCZ21TGX Power Adapter
If you decide to buy an non-Sony adapter, make sure to check both the voltage and amperage output. When choosing a new adapter, selecting the Sony OEM charger is the best one to choose. A universal AC adapter can be used if you absolutely need to. The Sony VPCZ21TGX AC adapter is needed for two reasons, charging the battery and to provide a source of power for the unit. Due to the fact that one Sony adapter powers multiple other machines, be certain you select the correct one for the VPCZ21TGX model.

- Battery does not charge up completely
- The unit will not operate while just using AC power
- Most Sony AC adapters will get very warm to the touch when plugged in for 10 minutes or more
