Confusion Between "Hibernate" And "Sleep"

Hi,

I've just replaced my desktop PC and have migrated from Win 10 Home to Win 11 Pro. I am trying to schedule backups to run overnight (local and cloud). This ran for years without issue on my old Win 10 machine. I think I need my computer to be in sleep mode rather than hibernate when I am not using it. I am basing this on the following definitions, picked up on the Community:

Sleep - All non-essential activities and drivers are stopped and the processor goes into power-conservation mode

Hibernate - The current system state is stored to hard drive, and the system powers off

My understanding of that is that if I put the computer into Sleep mode then any scheduled task will wake it up and run unattended. This certainly seemed to happen with Win 10. In Hibernate mode nothing will run unless the system is first woken up through the keyboard or mouse. Is this understanding correct?

In Settings / System / Power / Screen, Sleep and Hibernate Timeouts I only get settings for "Turn my screen off after" and "Make my device sleep after". There is no setting for Hibernate. However when the system reaches the "Make my device sleep after" time it hibernates! Everything shuts down and no scheduled tasks will run. When I set up a task in the Scheduler I check the box "Wake the computer to run this task" but nothing happens.

Please can someone advise how I can set up my system so that it goes into sleep mode overnight so that it can be woken by scheduled tasks.

TIA

    Hello

    Thank you for posting in Q&A forum.

    Here are a few steps you can try:

    1. Check Power Options:

    • Go to Settings > System > Power & sleep > Additional power settings.

    • Click on Change plan settings next to your selected power plan.

    • Click on Change advanced power settings.

    • Expand Sleep and ensure Allow wake timers is set to Enable.

    1. Task Scheduler Settings:

    • Open Task Scheduler.

    • Find your task and double-click to open its properties.

    • Go to the Conditions tab and ensure Wake the computer to run this task is checked.

    • In the Settings tab, check Run task as soon as possible after a scheduled start is missed.

    1. BIOS/UEFI Settings: Look for power management settings and ensure wake timers are enabled.
    2. High Precision Event Timer:

    • Open Device Manager.

    • Expand System devices and ensure High Precision Event Timer is enabled.

    1. Check for Conflicting Settings:

    • Ensure that no other power settings or maintenance schedules are conflicting with your task.

    I hope the information above is helpful.

    If you have any questions or concerns, please feel free to let us know.

    Best Regards,
