So I had a problem with sleep not resuming at all, instead going to Asus 0E boot error "Microcode not found". Then I realized I had recently tried enabling "Xeon Phi support" at BIOS and disabling it made the resume work again.
But meanwhile I found out something very strange for me. While resuming from sleep didn't work, I tried total powering off, removing the power cable altogether. There was still some power sucked out of a USB hub, making some leds lit, so I even removed the guilty USB cable. No power at all for the PC. Still, when I put power back on and basically booted from "zero", Windows 7 still resumed to full state back to when it was originally put to sleep.
So I thought ok, maybe I accidentally did hibernate instead of sleep and that would explain how it reverted to the snapshot with all applications in use. But no, it indeed was the sleep state. The states totally differ: hibernation = no power led and sleep = power led blinks.
My question is, how is it possible that putting sleep, then pulling the power plug off (and waiting for many minutes), then it is still possible to resume? It says "Resuming Windows" when I resume (push the power button on) after the power plug off.
Now that my PC (Asus P9X79 WS with i7-3930K) is in normal order, it takes about 27 seconds to go to full sleep state and about 7 seconds to go from sleep to full working order. The resume is pretty fast so I would imagine that is resume from memory? Is it hibernating to hard disk when I do sleep? Is it both hibernating to disk as a backup and maintaining the memory in sleep but alive state?
