    How to Enable or Disable to Allow Wake Timers in Windows 10


    A wake timer is a timed event that wakes the PC from sleep and hibernate states at a specific time. For example, a task in Task Scheduler set with the "Wake the computer to run this task" check box checked.

    Important wake timers are a new class of wake timer in Windows 10 that includes things like reboots after a Windows update that requires one. They supersede all other settings.

    This tutorial will show you how to enable or disable to allow wake timers to wake the computer in Windows 10.

    Allow wake timers.. checkbox is missing from my Power & Sleep advanced settings on one laptop but not the other (both Win10 v1909)! Fortunately the one that does have it is the one that was waking daily for UpdateOrchestrator scheduled tasks. Since I unchecked the wake, all is quiet. (fingers crossed)

    Hello WaterCat,

    The available power options can vary per system depending on its hardware and settings.

    Luckily, you can easily add Allow wake timers back to Power Options using an option in the tutorial below.

    My Desktop turns on constantly regardless of whether I put it to Sleep, Shut Down, or Force Shut Down. It might turn on instanly, after 10 minutes, after an hour, near midnight etc.

    There are several Tutorials here that deal with this . . .

    Hello Paul,

    I would say the first step is to ID the wake source. Once you do that, you can see about disabling it.

    I will probably have to do that in the morning now. I will report back when I have narrowed it down, thanks again.

    Hello @Brink,

    This is what I have discovered after running the procedures in the link you provided . . .

    Most showed this . . .

    . . . but I found a few of these further down . . .

    Enable or Disable Wake Timers in Windows 10-image.png

    . . . and then I found this . . .

    Enable or Disable Wake Timers in Windows 10-image.png

    What I was doing was to immediately shut the desktop down. Then it would startup again immediately or after 10 minutes, after an hour, near midnight etc. I have to switch the power off to stop it!

    Thanks in advance.

    @Paul Black,

    It looks to be your network adapter is waking the computer.

    Have you already unchecked the Allow this device to wake the computer box for this network adapter using option 2 below?

    If your ethernet is waking your computer, try this quick check. Open Device Manager and locate your ethernet device - it's probably under Network controllers. Double click on it and see if there's a tab for power management where you can uncheck an item to allow it to "wake" your computer.
