Suspend to RAM

This state offers significant power savings as everything in the system is put into a low-power state, except for memory, which is placed into the self-refresh mode to retain its contents.

To suspend to RAM:

$ echo mem > /sys/power/state

To wake up:
There are a few ways to wake up from suspend.
For example, using the RTC you can wake at a specific time (see the RTC section).
Another way is to push a button on the board which is set as wakeable.
