+ help
+ Enable this option if all devices on your system support the
+ D3Cold power management state. The D3Cold state is a low-power
+ state where the device has been powered down and is no longer
+ able to maintain its context. This state can help reduce
+ overall system power consumption, which can be beneficial for
+ energy savings and thermal management.
+
+ Please note that enabling D3Cold support may break system
+ suspend-to-RAM (S3) functionality.
