difference between "suspend to standby" and "suspend to ram"

nappaji · 08-23-2006, 08:03 PM

When I do cat /sys/power/state, it comes up with
standby mem

What is the difference between the two?
i.e. what is the difference when I do
echo -n standby > /sys/power/state
echo -n mem > /sys/power/state

Both the above commands seem to suspend the system?
What is the difference between suspend to standby and syspend to mem

I am using Puppy 2.0.2 kernel version 2.6.16.7

Thanks

It sounds like someone has misnamed the "suspend to standby" option; it should probably be "suspend to disk". "Suspend to RAM" saves a copy of everything you are doing in the (non-permanent) memory of the computer; Suspend to disk saves a copy in the swap partition of the disk.

(The swap partition is used when the computer runs out of memory, to give the impression that it doesn't).
