so there are in fact two on there.

Set the above as required (research probably needed to determine those settings)

Echo the "memory" power state into /sys/power
(Exact commands accepted may depend on which of the three kernels your devices runs - learn those by cat'ing the same entry).

Then wait.

The above should only depend on the kernel's interface to the hardware it is running on. "Below" any application programs.
