"And the reason Hibernate is important for me, is that unlike the schizophrenic battery draining sleep mode, the machine actually stays OFF until I turn it on. And Hibernate restoration is super-fast on these computers due to the SSD, and Windows 8.1."
I don't want to get in a pissin' contest here, I just want to convey what's common sense. Just for S&G I timed how long it takes from my usual shut down mode to get to the password prompt. It took 10 seconds.
I didn't time hibernation to password prompt because just the thought of hibernating my machine runs chills up and down my back. It doesn't seem to me to be worth hibernating or sleeping my machine when I'm not going to use if for awhile.
If I was worried about running down the battery, shutting it down would prolong it even more then sleep or hibernation.
