Suspend to RAM (Deep Sleep)

Deep Sleep AKA Suspend-to-RAM is a low-power mode that allows an embedded device to retain its state in RAM while the processor is turned off. This can save a significant amount of power, especially in devices that are battery-powered.

In order to enter deep sleep, use the following command:

# pm-suspend
