On Windows hosts, Workstation provides experimental support for guest operating system ACPI S1 sleep. Not all guest operating systems support this feature. Common guest operating system interfaces for entering standby mode are supported.

By default, ACPI S1 sleep is implemented in Workstation as suspend. You can use the Workstation Resume button to wake the guest operating system.

You can implement ACPI S1 sleep as power-on suspend. The guest operating system is not fully powered down. This feature can be useful for test and development scenarios. You can wake the virtual machine through keyboard input, mouse input, or by programming the CMOS external timer.
