Comment 6 for bug 882040

Hybrid-suspend is the process where the system does everything it needs to hibernate, suspends instead of shutting down. This means that your computer can wake up quicker than for normal hibernation if you do not run out of power, and you can resume even if you run out of power. s2both is an hybrid-suspend implementation.

*Pay attention to the wording, that it does everything that it needs to hibernate, but suspends instead of shuts down. If the computer runs out of power, nothing is lost as it's also been saved to disk, not just in ram.

Ubuntu should use only one suspend method: the hybrid suspend method.
