    Only works with ssd, however.

      Just let it die, like all the other intel proprietary crap that only works half the time.

        My SSD based laptop resumes as fast as I can open the lid, displaying the KDE lock screen. The OS is on a small 20gb SSD and the rest on a 500gb platter drive.

          I guess the mistake in the article is that it calls it 'suspend-resume' when it should be called hibernate (or suspend to disk vs suspend to ram).

          Suspend to ram is super fast, even on my 2004 old laptop. Hiberation, now that is slow, it first does a near full suspend, then writes the ram to swap. Booting takes longer, It has to start the bios as normal, load the kernel as normal and that then checks for the presence of the ram dump in swap and loads it.

          So speeding up hibernation can be quite interesting if that's accelerated, but only partial usefull. Suspend (to ram) is fast as it is, so 'who cares'.

            Yeah, as far as I can tell, this is suspend-to-disk, but mostly implemented at a BIOS level instead of OS. So, like hibernate it's a complete power off rather than a sleep. But presumably the BIOS support speeds things up a lot - presumably skipping boot loaders and stuff...

              How would this work in a multi os set up where two systems are set to hibernat? Come to think of it what happens if you hibernate on linux installation and then try and hibernate another one.

                If you hibernate on linux, how would you boot to another OS?

                  I guess Rapid Start woudn't allow this as it is at the bios level, but with normal hibernation you still get the bootloader where you can pick what to boot in to. Having both a Windows and Linux installation hibernated works fine, but i think you might get some issues with two linux systems that share swap.

                    when you resume from suspend the only thing that takes a bit is the re-connection of the network.
