state: Suspend-To-Idle ACPI state: S0 Label: "freeze"
This state is a generic, pure software, light-weight, system sleep state. It allows more energy to be saved relative to runtime idle by freezing user space and putting all I/O devices into low-power states (possibly lower-power than available at run time), such that the processors can spend more time in their idle states.
This state can be used for platforms without Power-On Suspend/Suspend-to-RAM support, or it can be used in addition to Suspend-to-RAM (memory sleep) to provide reduced resume latency. It is always supported.

TDE Powersave offers 4 states according to the source (factually 3 on my system):
- Suspend2RAM -- this is obvious
- Suspend2Disk -- obvious, too
- Freeze -- hmm, anybody knowing what this actually is? (in the code it uses
the Suspend2RAM icons but calls it's own method)
- Standby -- according help this is either a DPMS screen standby with the
system otherwise running on power or combined with a Suspend2RAM??? What is it really?
And I'm wondering where my most favourite suspend mode is hidden:
"Suspend2Both" aka "Hybrid Suspend"
This mode sets up the swap area as for Suspend2Disk AND then does a Suspend2RAM. The net effect is, that you normally have quick resume from RAM, but should power fail, nothing is lost as you can resume from disk. Essentially a failsafe suspend ... Its the only suspend-mode I you for desktop systems, and my prefered mode for laptop lid-close action as it always does "the right thing" (at little cost).
So, is "Freeze"="Suspend2Both" or can we introduce "Suspend2Both" (if the machine and swap configs allows)?
