    What is the point of "Check your Power Options to make sure that the Critical battery action and Low battery action settings under Battery are not set to Hibernate. (see screenshot below)" while the screenshot shows that Critical battery action is hibernate?
    What happen if I disable hibernation and my laptop battery is very low?

    Hibernation saves data to a file.
    Sleep saves data to RAM.
    With a dead battery RAM data likely disappears whereas the hibernation file can be reopened.
    Hibernation consumes less energy than sleep extending battery life.
    So in a notebook if it is used as a desktop replacement then you can disable hibernation.
    And if the notebook is using battery power and battery power is low make sure hibernation is available to reduce power consumption and possible data loss.

    In addition to what zbook posted, that step is there as part of making sure Hibernate is fully disabled when you don't want it enabled.

    If I still set Critical battery action as hibernate after disabling hibernation from command line, will it hibernate when my battery goes low? I think the screenshot for this step is quite confusing.

    The screenshot is just an example of the default settings and what it looks like set with Hibernate. The instructions in the step is what is important.

    If you disable hibernate, it will not sill hibernate even if set in Power Options. For some, it has caused a black screen or other issues having Power Options still set to Hibernate when it has been disabled.

    Hey all,

    Talking about this hiberfile: I have just done a fresh Windows Install (version 2004) to a 500GB SSD. This is a desktop pc and I never use the hibernate function. There is obviously no battery either. Fast start up is enabled by Windows by default with the note that it is recommended). I presume that turning off hiberfile is a good idea though? I have tested turning off Fast Startup (checkbox in the Control Panel Power Menu) and I really can’t see a difference in the boot time, so before I turn off permanently just want to be sure this is still best practice?

    I turned hibernate off using the elevated command prompt line and my available disc space went from 325GB to 331GB, so I did recover 6GB. I have 16GB RAM installed. While I am not in desperate need of the space and I cannot see a difference in boot time with fast start enabled, not sure if I should go against Microsoft’s “recommended” setting?

    Hello Greg,

    Fast Startup is really helpful when you have a slower spinner HDD.

    Since you have a fast SSD, you most likely will not notice any difference with Fast Startup off.

    If you have a M.2 or NVMe drive, you definitely will not notice any difference with Fast Startup off.

    In your situation, I would disable Hibernate (if you don't use it) to also disable Fast Startup and free up the drive space.

    Thanks Brink! Turned it off. I might even do this on my laptop. It has a NVMe drive and 16GB Ram, and I never use Hibernate on it either. I might use Sleep on occasion but never used Hibernate.
