    The goal is to have all of my computers either in Sleep or Hibernation mode after hours but have them wake up to install Windows Updates when they are available.


    If I have the computers Shut Down at the end of the day, the end user can get stuck with Windows Updates immediately after turning the computer on. The current solution is to leave the computers on 24/7 but this is not ideal long term.


    If I have my computers go into Sleep or Hibernation will they automatically wake up throughout the night to install updates? I'm okay if they don't go back to Sleep/Hibernation; the important thing is that they can still start the update when in that state. Thanks!

    :)

    Hibernate mode Vs Sleep Vs Hybrid sleep.

    I'm starting to lose track of what we're disagreeing on. I can't say what was on the mind of whoever designed the technique in the past, but today it is a tool available to any supporting platform where the users need it. Hybrid sleep is functionally a suspension to disk without clearing the ram, at its core it is a hibernation. Arguing which method is for which platform is -with all due respect- a waste of time. I would agree to the argument that Hybrid sleep is more versatile than simple hibernation, though, but that doesn't make hibernation a non valid method of suspension on desktops. And if someone intended for long down-times or expected power loss, the differences between hibernation and hybrid sleep become inexistent.

    For the frequent blackouts part, we have to consider the scope of the issue here: whoever opts to use any suspension method, hibernation, sleep or hybrid sleep, does so explicitly to avoid shutting down the computer (for whichever reason they wanted). Anecdotal example: I'm off to work in the morning, but I do not want to close all the software and web pages I have open (and they can be many) and restart them later, so I have the choice of either sleep or hibernate (or hybrid methods), but with any S state less than 4, I run the risk of a blackout forcing me to what I avoided shutting down for, so I elect to use hibernation (or hybrid sleep, of which the hibernation part is what's needed).

    A UPS is indeed a must have, but alas, not all of us live in the first world!


    VRAM isn't wiped post-wake up, per se. The only way to wipe the entire memory is relieving if of power. Hibernation does have that effect in the suspension process (going into hibernation), upon waking up it repopulates the memory with what was occupying it before turning off (though I don't know if it was actually this simple).
    What was I referring to in my previous post is Windows' memory manager's functionality. When a process is closed (eg: Alt+F4ed the main window, killed in task manager, etc), all its memory heap is then freed up for other processes to use. So, any memory that is used when a computer wakes is for actually running processes, waking up won't reserve memory for anything else (other than hardware, I guess?)

    Computers can be weird. I once had a recurring issue with Microsoft's Security Essential where it starts eating up all my ram after waking up from sleep. And I'm talking about 20GB of physical memory! Still don't know what caused that bug though. Couldn't reproduce it in later Windows installations on the same hardware either.
    And don't get me even started on those cheap Chinese hardware!

    Hibernate mode Vs Sleep Vs Hybrid sleep.

    Bad question. Not specific enough.

    Hibernate is for notebooks, not PCs. And it is important to note the OS used too. Windows 10 with DDR4 is designed take special advantage of the hybrid sleep mode. Previous versions of Windows and DDR3 don't provide the same capability.

    Hybrid sleep is primarily for desktop PCs and this is what I use and recommend. With DDR4 and W10 your RAM goes into a low-voltage state and maintains much of what was in memory during the hybrid sleep period. This allows the computer to wake that much faster. Having an SSD helps too.

    I never "shutdown" my computers, except to tear them down to lug outside for cleaning, or other maintenance. I never reboot, except when some update requires it.

    My normal routine is to use my computers several hours every morning, then I let them go into hybrid sleep until the next morning (or whenever I need to get back on).

    I have them set to turn off my displays after 10 minutes, then put the computer to sleep after 15.

    For the record, I am the bottleneck when waking the computer. When I wiggle the mouse or press a key, the computer wakes immediately, as do my monitors. Then they sit and wait for me to enter my password.

    Hibernate mode Vs Sleep Vs Hybrid sleep.

    I took in consideration your advice about Hybrid mode.




    To make it works is it just enough to activate it or do i need to do some others settings?
