Intel NUC D53427RKE Technical Product Specification

1.10.1.1System States and Power States

Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state.

Table 8 lists the power states supported by the board along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states.

Notes:

1.Total system power is dependent on the system configuration, including add-in boards and peripherals powered by the system chassis’ power supply.

2.Dependent on the standby power consumption of wake-up devices used in the system.
