Ele não está habilitado por padrão no Windows Server 2008, mas os servidores, por natureza, não são colocados normalmente como máquinas de mesa, mas são facilmente ativados:
- Click Start, click Control Panel, and then double-click Power Options.
- Under the power plan that is configured, click Change plan settings, and then click Change advanced power settings.
- Expand Sleep, and then modify the sleep configuration settings as appropriate for your requirements.
Note: If Sleep does not appear on the Advanced Settings tab of the Power Options dialog box, the computer does not meet the requirements to support the sleep feature. In this scenario, you may have to update the drivers or the devices on the computer.
